Boz Scaggs: Greatest Hits Live" (2004)
I was browsing around for some stuff to listen to, and I found this show:

Apparently the show was recorded with two Beyer mics placed on 15' poles near the soundboard and using a DAT recorder. To me, the sound is excellent with just enough crowd noise to give the proper live feel. I've listened to it through headphones and speakers and it sounds great either way.
(The picture above is just a random picture of the Dead playing live and is not from the same show as the recording.)
Check it out. 172 minutes of free music in MP3 or FLAC format.
