I'm on my third spin through this 6 cd box set and find it fascinating. I am sure the large set is even more fascinating, and owners of that also received MP3s of '65 live shows, something that probably would have set me over the edge to buying the big set if I had known that was part of the plan. This is actually taking me back three decades to when I was drumming in a few bands and rehearsing in my then garage apartment, learning material and arrangements and having some real intense times. No, the music was not "cutting edge" as this material is, but there was a comparable spirit and this set reinvokes some of that within me. Anyway, I'm so glad to have this version and can only imagine the fun that some owners of the big set are having!
