"About A Son" is interesting. Its just a bunch of sound interviews with Kurt mixed with footage of places around Washington and such. Some people complain that the footage is bland, since it has nothing to do with the band but I think it's a relaxing video to watch. Certainly at least more than the others which is always full of drama and dysfunction.
I remember loving "Do The Evolution" more on the Live On 2 Legs live album when I was younger (posted below), maybe check that out. The album version does sound kind of weird. Or Vedder at least sounds like hes on something, but to me it's at least different from the same old Pearl Jam sound..,. The lyrics are also really interesting
