My friend Keith was running 6 mics in Wilkes-Barre the other night, wanted to share. I have not even had time to listen to any of these yet, but his recordings are always top-notch. He was taping from the first row behind the soundboard, and at one point one of the Dead's sound guys (whom Keith has known for years) turned around and asked him for a hard copy, said he needed it for the band, as they weren't running an audience recording that night. :)
Here are links to download his 3 sources from Etree and Archive, and of course on Archive you can listen online in streaming audio too. These are listed in Keith's order of preference (he liked his old school mics best), although some have a different opinion...
