You might not know the name, but you know the guitar roar better than you think. Zakk Wylde is the man Ozzy Osbourne pulled from obscurity in 1987 after mentioning in a radio interview that he was looking for a new guitarist. And now he is heading with his crew to a small South Moravian town beneath a Renaissance castle. If you are looking for the best events in Moravský Krumlov in mid-August, here is your reason: the open-air Rock Castle 2026 in the castle park. Alongside the southern metal of Black Label Society, you can also catch the Finnish melodics of Sonata Arctica and the Florida legend Savatage, from which the multi-platinum Christmas phenomenon Trans-Siberian Orchestra unexpectedly grew. It sounds like a programme for a big city, but it all happens just a stone's throw from the castle walls.
Best events in Moravský Krumlov: what to focus on in mid-August
In mid-August, the best events in Moravský Krumlov converge on one name: Rock Castle 2026. It is an open-air rock and metal event in the castle park, and it is worth building an entire weekend plan around it.
According to our data, Rock Castle takes place on 13 August 2026 in the Castle Park in Moravský Krumlov. The exact programme and set times are still being finalised over the summer, so always check the complete line-up and schedule on the festival's official channels. In this guide we are not going through the entire bill, but focusing on three acts around which you can build the experience even if you are not yet sure what to expect: Black Label Society, Sonata Arctica and Savatage. Each plays a different kind of metal, and it is precisely that variety that makes Krumlov an interesting stop. Those who follow the heavier scene will find other big names discussed in connection with the festival in our database, such as German Powerwolf or American thrash act Testament. Whoever ends up on the bill, the combination of a Renaissance castle and loud guitars is reason enough to come - it is not something you can easily replicate elsewhere in the Czech Republic.
Black Label Society and Zakk Wylde: southern metal beneath the castle
Black Label Society is a one-man band with enormous charisma. Zakk Wylde has led it since the late nineties and it will most likely be the strongest experience of the whole event.
Before Wylde started his own band, he was already a star. As a teenager from New Jersey he pushed his demo tape to Ozzy Osbourne and became his long-time guitarist; he co-wrote modern Ozzy classics such as "No More Tears" and "Mama, I'm Coming Home". When the two parted ways after recording the Ozzmosis album, Wylde released his solo record Book of Shadows in 1996 and soon launched his own project. Black Label Society was formed in Los Angeles in the late nineties, the debut Sonic Brew came out in 1999 and Wylde played almost every instrument on it himself. By 2026 the band has twelve studio albums to its name, including the commercially most successful Mafia from 2005.
The sound is built on heavy, whisky-soaked riffs that reviewers like to compare to a meeting between Lynyrd Skynyrd and Slayer, and surprisingly fragile piano ballads. Wylde is hard to miss at first glance thanks to his bullseye-patterned guitars, and his devoted fans call themselves Berserkers. Live it is loud, greasy and yet personal, because Wylde plays not just for technique but for emotion. Anyone wanting to know exactly when they play and where to buy a ticket will find the link on our event page Rock Castle 2026.
Sonata Arctica: Finnish power metal you will be humming on the way home
Sonata Arctica is the polar opposite of Wylde's southern heaviness: fast melodies, keyboards and clean vocals. Anyone who likes metal they can hum on the way home from the show will be right at home.
The band comes from the small Finnish town of Kemi and their beginnings make a nice story for those who remember. The group formed in the mid-nineties as a hard rock outfit, first under the name Tricky Beans, then Tricky Means. They worked their way towards the fast power metal style of their compatriots Stratovarius later on, and the change of sound came with a change of name to Sonata Arctica. The breakthrough came with the debut Ecliptica in 1999, which critics praised and which sent the band into the top tier of melodic metal alongside names like Edguy and Kamelot. Vocalist and main songwriter Tony Kakko and drummer Tommy Portimo are still the only remaining founding members, so on stage you see a direct line back to the very beginning.
The sound is textbook: sweeping melodic compositions, meaty riffs and rich production with clean vocals. Interestingly, Kakko himself long maintained that many bands were better at pure power metal, and from the album Unia in 2007 Sonata Arctica steered towards a more progressive, calmer rock sound. The setlist therefore typically alternates between blazing anthems from the early records and more elaborate newer pieces. For a festival audience it is a rewarding band, because the choruses are singable even from the back rows. We added Sonata Arctica to our database precisely because they are a reliable draw at events here.
Savatage: the band that gave birth to Trans-Siberian Orchestra
Savatage is the oldest name of this trio and at the same time a story full of twists. Anyone who knows the Christmas hit "Christmas Eve (Sarajevo 12/24)" may not realise it was born right here.
The band was founded in 1979 in Florida by brothers Jon and Criss Oliva, initially under the name Avatar. Over two decades and eleven albums, Savatage built a reputation as one of the most inventive American metal bands; albums such as Hall of the Mountain King and Gutter Ballet are still considered classics of a genre that blends thrash, power metal and progressive rock with elements of rock opera. In 1993 tragedy struck when guitarist Criss Oliva was killed in a car accident. Jon decided to carry on in the band in his brother's memory alongside producer and co-writer Paul O'Neill.
And here is the detour you would not expect from a metal band. On the concept album Dead Winter Dead from 1995, the instrumental "Christmas Eve (Sarajevo 12/24)" appeared - a metalised version of "Carol of the Bells". The track unexpectedly caught on radio and became the springboard for Trans-Siberian Orchestra, the symphonic metal project of Paul O'Neill and Jon Oliva, which grew into one of the highest-grossing concert brands in the world and collected gold and multi-platinum records. Oliva himself recalled that in twenty years Savatage had not earned as much as TSO made in a single Christmas season. The band took a long hiatus after 2001, but made a one-off return at Wacken Open Air, and their influence on symphonic and progressive metal is still felt today. You can find the Savatage profile in our database so you know who to look for at the event.
The castle park and Moravský Krumlov around the festival
The magic of Rock Castle is not just the bands but also the setting. The castle park in Moravský Krumlov is itself a reason to arrive early and stay longer.
The site sits beside a Renaissance castle in a town above the Rokytná river. It is not a bare field with a stage but a historic garden with mature trees, which comes in very handy in the August heat because shade is easy to find. The town itself is small and quiet, so the festival crowd and the surroundings complement each other nicely. Anyone who wants a break from the decibels can head into the centre or find a quieter programme.
In our calendar, Moravský Krumlov also has a slower pace. Right in town you can drop in on a soy candle-making workshop at the local Cultural and Creative Centre, which is a pleasant counterpoint to a full day of guitar assault. If you are planning trips to the surrounding area or want to compare what is happening elsewhere in the country, check our events calendar or go straight to the overview of concerts. A few tips to pack: the park involves moving over uneven ground, so comfortable shoes are a better choice than city trainers, and in August water and a hat are worth bringing.
Practical information: tickets and planning
A few things are worth sorting out in advance, especially tickets. For an open-air event in a small town, buying in advance and planning transport early are the most important things.
Tickets for Rock Castle 2026 are on sale through Ticketmaster; you will find the link to the specific sale directly on our event page Rock Castle 2026. Keep an eye on prices and any additional sales channels on the festival's official website, as that is the number one source for up-to-date information about the site, camping and the programme. Capacity at events like this tends to be limited, so if you want to sleep on site, it is better to sort that out well in advance.
The final piece of advice is simple: before you go, check the official programme for exact times. At a multi-band event you cannot catch everything without a plan, and if the trio of Black Label Society, Sonata Arctica and Savatage is what draws you, you need to know when they go on. If Krumlov leaves you wanting more heavy music in general, take a look at the other names in our database so you know who to look for at future events.
