A series of personnel changes in the late 1990s was capped by the departure of Betts. The band re-formed once more in 1989, releasing a string of new albums and touring heavily. 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. The album included Betts's hit single " Ramblin' Man" and instrumental " Jessica", which went on to become classic rock radio staples and placed the group at the forefront of 1970s rock music. Following the motorcycling death of bassist Berry Oakley 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. Group leader Duane Allman was killed in a motorcycle accident later that year – on Octo– 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". It features extended versions of their songs " In Memory of Elizabeth Reed" and " Whipping Post", and is considered among the best live albums ever made. Their 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 was an artistic and commercial breakthrough. Subsequently based in Macon, Georgia, they incorporated elements of blues, jazz, and country music, and their live shows featured jam band-style improvisation and instrumentals. 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).
