The Allman Brothers Band is an American rock band once based in Macon, Georgia. The band was formed in Jacksonville, Florida, in 1969 by brothers Duane Allman (slide guitar and lead guitar) and Gregg Allman (vocals, organ, songwriting), who were supported by 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 instrumental songs.
The band achieved its artistic and commercial breakthrough in 1971 with the release of At Fillmore East, featuring extended renditions of their songs "In Memory of Elizabeth Reed" and "Whipping Post" and often considered one of the best live albums ever made. George Kimball of Rolling Stone magazine hailed them as "the best damn rock and roll band this country has ever produced."
