Lost Session is an interesting historical curiosity, but it is rather unsuccessful musically. John Mayall produced the record and he tried to move Albert King toward jazz. First of all, King's style isn't quite suited for jazz — he's too direct and forceful. Furthermore, the songs are simply skeletons — their only function is to let the band solo. And there are a couple of good solos, all of them from King. But ultimately, it's a forgettable exercise that should have been left in the vault.
