I must have watched the Rush: Grace Under Pressure tour video (on VHS!) dozens of times in high school. It holds up well. My current favorite concert of theirs is R30.

Another favorite is Oasis, There and Then (DVD). It catches them at their peak in 1995-1996, playing football stadiums, with tens of thousands of fans singing along. Really makes you feel like you're there. Really improved my enjoyment of "Live Forever". Crank up the bass!

Bears, beets, Battlestar Galactica.
