There are actually alot of big bands and big events that come through Tulsa. I have seen N.I.N, P.O.D., Primus, evenesence, Green Day, Pantera, Gravity Kills, Poe, Stabbing Westward, Limp Bizkit, Tool, and many more with in the last 8 or so years. Plus there is still the Edge B-day show, Rocklahoma, and other tours that have originated or come here.
Also OKC is only an hour and a half away (if not less) and they have some pretty huge bands that go through there.

The local scene here is great too, you would be suprised at what a "bunch of hicks" can do. Almost any bar that is worth going to here has live bands at least once a weekend if not a different band every night of the weekend. Now given there are bands that uck that some how make it into those places, the scene here is actually really strong. I have always been pleased with the locals.

There have been alot of big names come out of Oklahoma haha, for instance Hinder, Billy Joe from green day is from norman, and who could forget Garth Brooks haha (yeah I went there ba-booosh-ka!).
