Personally, as someone only recently getting into the blues, and especially the 60's British blues boom, I thought this was a pretty good album. Peter Green's guitar playing is excellent, especially as he was filling the recently departed shoes of Eric Clapton. Tracks like Supernatural, and for me, The Stumble, particularly stick out, and for any Peter Green fan this album is a must. Otherwise, this album is still quite good, with Mayall managing quite a degree of feeling in his vocals, and the band as tight as ever. All in all, pretty damn good.
