What are some good bands?

Kings of Leon, Anthrax, Five Bolt Main, System of A Down, seriously the best thing for you to do would be to go to amazon.com and search for one of your favorite artists. Click on one of their albums and there will be a list of "other things people bought who liked this album" also there's some great user lists too. I have no doubt you'd come up with a score of people with complete lists of some of their fave bands and artists that fit into this catagory.
