Wow. I forgot about the Inner Mounting Flame. I had it on cassette eons ago and burned the tape out from listening to it.
I bought the Bolin box set when it came out and was disappointed and turned around and sold it. I remember a song that he did on an LP which did not make it to the box set (which was one of the reasons I bought it the thing). It was a song titled "coke" or "peruvian flake" or something like that. It had some hot guitar, but I haven't heard it in years so my memory may have enhanced it.
By the way, I listened to Quadrant 4 before I went to work this am. It still held up!
