chadwick was not big on letting people get soundboard patches, let alone multitrack soundboard patches so there are probably not many trio shows that were taped anything above a matrix quality. What made zone 1 unique was dobson did multichannel records of several shows and then mixed all the jams back together, this beef barley guitar solo over that shows hard luck harry piano, etc. A lot more went into that album than just the band playing one night and then him releasing the soundboards. It\'s a very creative piece of work.
