Boris Grebenshikov is a Russian artist who worked with Annie on Dave on his first English language album called Radio Silence.
Boris Grebenshchikov (born 27 November 1953) is a prominent member of the generation which is widely considered the "founding fathers" of Russian rock music. Due as much to his personal contribution as to the lasting success of his main effort, the band Aquarium (active from 1972 until today), he is a household name in Russia and much of the former Soviet Union. Grebenshchikov is frequently referred to as BG (Russian: ??) (pronounced "Beh-Geh"), after his initials. He is often called the 'Grandfather of Russian Rock'.
