This album collects together out-takes and left overs from John Mayalls time at Decca. As such it has some pretty standard stuff along with some blinders, because the ratio is about 75/25 to the good stuff, this is why it doesn't deserve five stars. There's no Eric Clapton on here, but you do get eight tracks with Peter Green and they are amazing. The Green numbers range from delicate through to heavy, and at each level Green shows his mastery of the guitar and the genre. For those eight songs alone its worth its price, if you like the rest then even better.
