So a bunch of bands have launched or relaunched their websites recently. Check out the following sites for info on all your favorite bands:
Green Day Me First and the Gimme Gimmes Jets To Brazil Dashboard Confessional Cursive Small Brown Bike
I'm sure there are more, but this is all I could remember off the top of my head. Most are fairly graphically intense, too, so make sure your computer is up-to-date. Now go rock it out.
