The Basement Tapes

Wikipedia - "The Basement Tapes is a 1975 studio album by Bob Dylan and The Band. The songs featuring Dylan's vocals were recorded in 1967, eight years before the album's release, at houses in and around Woodstock, New York, where Dylan and the Band lived. Although most of the Dylan songs had appeared on bootleg records, The Basement Tapes marked their first official release. ... While some of the basement songs are humorous, others dwell on nothingness, betrayal and a quest for salvation. In general, they possess a rootsy quality anticipating the Americana genre. For some critics, the songs on The Basement Tapes, which circulated widely in unofficial form, mounted a major stylistic challenge to rock music in the late sixties."
