There's not much happening here. By the time Positive Vibrations was released, Ten Years After had run out of gas. Leader Alvin Lee had already released two solo albums, "On the Road to Freedom" and "In Flight," and the band was simply going through the motions on this album. The band broke up following its release. ~ Jim Newsom - All Music Guide
