Good Ten Years After album, their fourth. It's not "A Space In Time" (definitely their best), but lots of energy, and Alvin Lee...well, what can you say? He's still one of the best to this day. Speed, finesse, and soul, a rare combination. You can feel the emotion of every note he plays, as if his emotions came right out through his fingers. An incredible depth of feeling.
