HENYCH 666 is a Prague metal band led by bassist and vocalist Vlasta Henych, who founded it in 2010 after leaving Törr - the cult Czech group he had fronted for 25 years and which was among the first black metal acts in the Eastern Bloc. The band blends black metal with thrash and industrial elements, drawing on both Törr's back catalogue and original material. After releasing the EP Psychonaut (2011) and a 2016 single, the group returned in 2023 with a new lineup featuring guitarists Aleš Hampl and Yan Havlín and drummer Petr "Herr" Miler.
In November 2025, HENYCH 666 performed on a joint tour with American band Mindbender, which included stops in Prague, Ostrava, Uherské Hradiště, and Bratislava.
In October 2024, HENYCH 666 performed the complete Törru album "Institut klinické smrti" (1991) live for the first time in history at a special concert at Prague's KD Barikádníků.
For the October 2024 concert, a remastered re-release of the Törru album "Institut klinické smrti" (1991) was released on CD, LP, and streaming services under the license of Warner Music Czech Republic.
After a three-year COVID-19 break, HENYCH 666 returned in 2023 in a new lineup: guitarists Aleš Hampl and Yan Havlín joined Vlastovi Henychovi, and Petr "Herr" Miler took over drums.
