Disclaimers - I have the CD/DVD-V set, not the Blu-ray from the Sailor's Tale box set. The album was totally new to me, and I don't have the related releases Ladies of the Road or Summit Studios.
Upsides: The Summit Studios tracks sound great both in Stereo and in quad. The Summit Tracks sound near perfect and the performances are strong. On my setup, the banter between Summit tracks is very quiet compared to the songs. The Schizoid men tracks are an interesting and engaging series. These bits are in heavy rotation in the car (stereo) and at home (quad).
Downsides: Just as it was advertised, the CD is near bootleg quality. It's a painful listen compared to the Summit Studios tracks. I do not plan to put the cd in heavy rotation. The "new sequence stereo" of the Earthbound album on the DVD is fine, albeit with the same sonic limitations of the cd. There is an extended version of "Sailor's Tale" from Jacksonville that should have been left unextended. The drum solo sounds terrible and is terrible. It's like listening to "The Grand Vizier's Garden Party" from Pink Floyds's Electric Moo played at full blast while inside a tin shed.
That being said, I think this is a must buy. At this price, the Summit Studios alone would have been sufficient. This is a really cool document of that time and I'm not sure what else there is at this quality. Looking for other really high quality shows from this lineup sent me back to the Zoom Club shows of April 1971, many months before Islands was recorded and released.
I'm very happy with this purchase compared to some giant box sets with only three discs that recently came out.
Sound quality 5 for CD/Earthbound tracks, 9 for Summit Studios
