Released on this day in 1965 — 58 years ago — the Byrds' debut album, Mr. Tambourine Man, marked a critical beginning of the folk-rock revolution. In just a few months, the Byrds had become a household name, with a #1 single and a smash-hit album that married the ringing guitars and backbeat of the British Invasion with the harmonies and lyrical depth of folk to create an entirely new sound.
