Khrennikov's Seven (Russian: Хренниковская семёрка or Семёрка Хренникова) was a group of seven Russian Soviet composers denounced in 1979 at the Sixth Congress of the Composers' Union by its leader Tikhon Khrennikov for the unapproved participation in some festivals of Soviet music in the West. Khrennikov called their music "pointlessness... and noisy mud instead of real musical innovation". The seven were listed in the following order: Elena Firsova, Dmitri Smirnov, Alexander Knaifel, Viktor Suslin, Vyacheslav Artyomov, Sofia Gubaidulina, and Edison Denisov. These composers subsequently suffered restrictions on performance and publication of their music.
