O5 a Radeček is a pop-rock band from Šumperk in the Jeseníky foothills, performing with the same lineup since 1994. Their 2004 song Praha (Jedna holka...) broke them into the mainstream, and they have since become one of the most in-demand live acts in the Czech Republic. The 2023 hit Hory won the Český slavík award for Song of the Year, and their 2024 album HoraLove earned a Platinum disc along with three Anděl Award nominations.
The band announced its largest concert to date: on February 26, 2028, it will perform at the Prague O2 Arena with the Moravian Philharmonic Orchestra Olomouc.
The Valentine's concert at O2 universum was sold out long in advance; the band performed it with the Moravian Philharmonic Orchestra Olomouc.
O5 and Radeček released a joint single Albatros with singer Lipo.
The band released a live EP Živě s filharmonií recorded with the Moravian Philharmonic Orchestra Olomouc.
The album HoraLove was released, recorded at the Berlin Hansa Studios with New Zealand producer Greg Haver; the band received a Platinum Record for it.
