The Allman Brothers Band is an American rock band formed in Jacksonville, Florida in 1969 by brothers Duane Allman (slide guitar and lead guitar) and Gregg Allman (vocals, organ, songwriting), as well as Dickey Betts (lead guitar, vocals, songwriting), Berry Oakley (bass guitar), Butch Trucks (drums), and Jai Johanny "Jaimoe" Johanson (drums). While the band has been called the principal architects of southern rock, they also incorporate elements of blues, jazz, and country music, and their live shows have jam band-style improvisation and instrumentals.
The group's first two studio releases stalled commercially, but their 1971 live release, At Fillmore East, represented an artistic and commercial breakthrough. The album features extended renderings of their songs "In Memory of Elizabeth Reed" and "Whipping Post", and is often considered among the best live albums. Group leader Duane Allman was killed in a motorcycle accident not long afterward, and the band completed Eat a Peach (1972) in his memory, a dual studio/live album that cemented the band's popularity. Following the death of bassist Berry Oakley later that year, the group recruited keyboardist Chuck Leavell and bassist Lamar Williams for 1973's Brothers and Sisters, which, combined with the hit single, "Ramblin' Man", placed the group at the forefront of 1970s rock music. Internal turmoil overtook the band soon after; the group dissolved in 1976, reformed briefly at the end of the decade with additional personnel changes, and dissolved again in 1982.
