Duane Allman's greatness was apparent on his recordings with the Allman Brothers, yet there was another side to the superb guitarist. For many years, he was a highly respected session musician, playing on cuts by Wilson Pickett, Aretha Franklin, King Curtis, Boz Scaggs, Delaney & Bonnie, and Clarence Carter, among others. By including those session cuts, as well as a sampling of his brief sojourn in Eric Clapton's Derek and the Dominoes and a few rare solo tracks, along with a number of representative Allman Brothers songs, the double-album Anthology winds up drawing a complete portrait of Allman. He may have recorded plenty of other material worth hearing, but this has the bare essentials for an excellent introduction and retrospective.
