I'm not sure if you were joking (because of the winky) but actually I do think it has some pretty damn good sound, both 5.1 and PCM stereo, the PCM is fairly good but the 5.1 DD definitely opens up the soundstage very nicely.
I'll second The Complete Monterey Pop Festival, the second disc of Jimi Plays Monterey & Shake: Otis at Monterey also features some fine audio....although throughout all of the discs I have to say that the rear surround applause effects do sound a bit canned most of the time...but that is very minor.
I wish I could say the same for Woodstock....the 5.1 DD track is OK but the entire film and soundtrack need an upgrade as this was one of the very first DVD's out there...give it an SE WB! The DTS track featured in theaters during it's re-release around...was it 94?...sounded great, but this being WB I seriously doubt we will ever hear that.
