Russian experimental/industrial/avant-garde group formed in March 1984 in Riga, Latvia (ex-USSR) by Nick Soudnick and Valeri Dudkin. More musicians joined soon after the first home-taped session, most notably Alexander Zhilin, who became the core member and Nick's closest collaborator.

The band's name in Russian, ЗГА, means "anything" but solely in the context of "non-visibility," i.e., "can't see anything." The word "зга" has no inherent meaning, and Russian linguists still debate its etymology.
