The Flying Burrito Brothers were an early country rock band, best known for their massively influential debut album, 1969's The Gilded Palace of Sin. Although the group is most often thought of in connection with country-rock legend Gram Parsons, in fact it endured myriad personnel changes through a series of break-ups and resurrections (sometimes due to Parsons' tendency to switch from band to band and project to project with no notice).
Ironically, the band best known as the "Flying Burrito Brothers" actually 'borrowed' their name from the original "Flying Burrito Brothers", composed of bassist Ian Dunlop and drummer Mickey Gauvin, bandmates of Parsons from the Boston-born International Submarine Band, plus any of a loose coalition of musicians, including Parsons himself from time to time.
