It's a heck of a lineup, you're right. Some great music as well. Sound is okay. (I have most of this also on TOCJ cds that sound better, in my opinion, but sure cost more too! This material sounds pretty good on this two cd set though).
I think there are seminal performances here that are a part of the beginning of the music that followed, along with sister dates on other labels by these artists. Tom Wilson was almost as careful and empowering a producer as Alfred Lion. You'll like this one I bet.
