Al Kooper, Al’s Big Deal / Unclaimed Freight: An Al Kooper Anthology, 1975 on Columbia.
Al Kooper was a co-founder Blood Sweat & Tears, played with the Blues Project as well as Dylan, and was involved in so many great projects. I’m a fan and tend to pick up anything I find crate digging that has him on it – found this 70s compilation on promotional labels at the Record Exchange in Salem, MA
