Ah, those halcyon days of pre-world-domination U2...you'll soon be able to set your wayback machine for 1983 via the release of U2's Live At Red Rocks on DVD and the remastered version of their contemporaneous live album Under A Blood Red Sky. Both are set to greet the 21st century on September 30, at which time you can either relive the spectacle all over again (for you oldsters) or experience it for the first time (ah, youth). How can you resist -- the white flag, the mullet, Bono's odd facial resemblance to Robin Williams (are we alone in noticing this?), most importantly, the sense of fun that the foursome had during the period in which they still remembered that they were a rock band and not a UN panel. This should be just the thing with which to school your snotty little brother who thinks the U2 story begins and ends with The Joshua Tree.
