Okkervil River is an American rock band led by singer-songwriter Will Sheff. Formed in Austin, Texas, in 1998, the band takes its name from a short story by Russian author Tatyana Tolstaya set on the river Okkervil in Saint Petersburg. They began as a trio made up of Sheff and friends he had met in his native state of New Hampshire but, over time, have gone through many lineups.
