Neschastny Sluchai (Russian: Несчастный случай, literally "Unfortunate Event") is a Russian rock band that was formed by Valdis Pelsh and Alexey Kortnev in 1983, while both men were students at Moscow State University.

[1][2] Despite being popular in Russia, the band is virtually unknown outside.

[3] The band leader, Alexei Kortnev, has repeatedly cited as major influences such bands as Queen, King Crimson, and Genesis.

[4][5] The band's lyrics are at the same time grotesque and sentimental while their music features complicated structures and melodic turns rooted in the prog rock of the '70s.

[5] The band's lyrics are usually short stories of ordinary people's life, written with good-natured irony.
