Two of Barry Goldberg's best albums from the late '60s, Reunion and Two Jews Blues, are combined on this single disc. There's some very hot playing on these two albums, particularly from Mike Bloomfield on Two Jews Blues, but they sound a little dated and don't quite burn as hot as some blues-rock albums from the late '60s.

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.
