May 10, The Eagles.
Not a lot of bands can do 3+ hours of greatest hits (except for 3-4 new songs), but these guys had everyone up and singing along to almost every number. And while their harmony is still great, maybe they don't hit some of the notes that they used to. On the other hand, Joe Walsh still plays his guitar as well as he ever has, and produces some great riffs. Totally outstanding sound system as well (in fact, probably the best I've ever heard, no distortion at all).
