He was also the founder of the conceptual art avant-garde project Kommunizm and psychedelic rock outfit Egor i Opizdenevshie.

Letov collaborated with singer-songwriter Yanka Dyagileva and other Siberian underground artists as a record engineer and producer.

At the beginning of his interest in poetry he was influenced by the Austrian poet Erich Fried.

Letov's favorite writers, who considerably affected his world view and writing style, were Andrei Platonov, Fyodor Dostoevsky, Henry Miller, Bruno Schulz, Flann O'Brien, Leonid Andreev, Ryunosuke Akutagawa, Kōbō Abe, and Kenzaburō Ōe.

[8] Poet Elena Fanailova stated that Letov was "[A] really fucked up and really free artist, whose main and only mission was to experience limits of his own freedom" and "certainly large, significant author, who created his own world – which, though, works only in the context of the post-Soviet civilization".
