This is a must-have for JPJ or those who collect Zeppelin material. This isnt the bone crushing rock n roll you expect but some good experimentation by Jonsey. With Jimmy Page on 2 tracks and Jon Anderson of Yes on 2 tracks,plus the bonus of Jones himself singing on tracks, I really enjoyed the various types of music on this. "Crackback" will remind you of the same hard hitting sound heard on Zep 4 while "Chilli Sauce" is all in the mind of Jones stepping away from Zeppelin and into his own. A sweet piece of work for sure and when you select this CD for the collection, dont forget to pick up "Zooma"also.
