"Mickboy" is a legend in the world of bootlegging. His "remasters" have a warm and analog-like sound to them, with great separation that jumps from the speakers. They sound nothing like the original.
This is a 3CD bootleg, of the March 17, 1975, show at The Seattle Center Coliseum, in Seattle, Washington, from those fine folks at Empress Valley, in Tokyo, Japan.
The (soundboard) audio is so good, it could be released officially, as is. Of course, if it was an official release, Jimmy would have rerecorded three quarters of the guitar parts, and Percy would have rerecorded all the vocals, and we'd be left with something akin to an alleged "live" Rolling Stones album. But this is what they really sounded like that night, and it sounds pretty damned good.
