Grazhdanskaya Oborona (Russian:
Гражданская Оборона, ), Russian for
Civil Defense, or
ГО, often referred to as
ГрОб, Russian for
coffin) were one of the earliest
Soviet and Russian psychedelic/
punk rock bands. They influenced many Soviet and, subsequently, Russian bands. From the early 1990s, the band's music began to evolve in the direction of
psychedelic rock and
shoegaze, and band leader
Yegor Letov's lyrics became more metaphysical than political.
