Grazhdanskaya Oborona (Russian: Гражданская Оборона, [ɡrɐʐˈdanskə(jə) ɐbɐˈronɐ]), Russian for Civil Defense, or ГО, often referred to as ГрОб, Russian for coffin) was one of the earliest Soviet and Russian psychedelic/punk rock bands. It 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 Egor Letov's lyrics became more metaphysical than political.
