Much like Super Session (the studio version of this record), this album suffers a little from happenstance: Mike Bloomfield had a habit of wearing himself out and he’s not present on all tracks (much like on Super Session where he was replaced for half of it by Stephen Stills). But he’s present on most (and Carlos Santana is one of his replacements).
So putting that weird little curiosity aside: this is pretty great live blues rock/jazz rock for its era and it’s one of the principle documents you can find of why Bloomfield is considered one of the great blues guitarists of his era and why Kooper was one of the great keyboardists of the same era.
It’s not for you if you don’t like jams but the playing is excellent and many of the covers are quirky (something Kooper did a lot during this era).
If you are a fan of either performer, or you are a fan of good playing, it’s worth checking out.
