Nice to see this one available on cd, and with the extra tracks, although I'm pretty sure all have been available elsewhere. The picture on the original LP cover was always a little irritating, because it showed a picture of Jeff Beck with the Yardbirds. However, although he is not on this recording, he may well have been a band member by the time it was released!
This is a good record of a Sonny Boy performance, although perhaps not essential. Having said that, he was such a master of his craft that anything by him is worth buying. The Yardbirds give suitably laidback and reverential backing, no doubt listening very hard for when Sonny Boy was going to change chords, because like John Lee Hooker and many others, the 12 bar format was a loose arrangement for him!
There are no blistering Clapton solos, but some nice touches which give an indication of the talent within.The rest of the band also do a very adequate back-up job for the main man (although Sonny Boy does a few numbers on his own, which feature some extraordinary harmonica playing).
Sound quality is good, and if you close your eyes you can almost imagine what it was like to be in the audience - I only wish I had been, as I never got to see Sonny Boy.
Packaging is very good, with excellent sleeve notes, making up a quality souvenir of the early days of British r&b meeting the original bluesmen.
