Note: Gregg and Duane Allman formed a band in Los Angeles called the Hour Glass that recorded 2 albums and toured up and down the West Coast opening for groups like Eric Burden and the Animals, Buffalo Springfield and The Doors in 1967 and 1968. The Bahr Gallery has several psychedelic posters featuring the Hour Glass and they are included with the Allman Brothers pieces.
The Allman Brothers Band was an American rock band formed in Jacksonville, Florida in 1969 by brothers Duane Allman (founder, slide guitar and lead guitar) and Gregg Allman (vocals, keyboards, songwriting), as well as Dickey Betts (lead guitar, vocals, songwriting), Berry Oakley (bass guitar), Butch Trucks (drums), and Jai Johanny "Jaimoe" Johanson (drums). The band incorporated elements of blues, jazz, and country music, and their live shows featured jam band-style improvisation and instrumentals.
The group's first two studio releases, The Allman Brothers Band (1969) and Idlewild South (1970) (both released by Capricorn Records), 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 considered among the best live albums ever made.
Group leader Duane Allman was killed in a motorcycle accident later that year – on October 29, 1971, and the band dedicated Eat a Peach (1972) to his memory, a dual studio/live album that cemented the band's popularity and featured Gregg Allman's "Melissa" and Dickey Betts's "Blue Sky". Following the motorcycling death of bassist Berry Oakley exactly one year and 13 days later on November 11, 1972, the group recruited keyboardist Chuck Leavell and bassist Lamar Williams for 1973's Brothers and Sisters. This album included Betts's hit single "Ramblin' Man". These tunes went on to become classic rock radio staples, and placed the group at the forefront of 1970s rock music. Internal turmoil overtook them soon after; the group dissolved in 1976, reformed briefly at the end of the decade with additional personnel changes, and dissolved again in 1982.
