I need some band ideas?

I know what your problem is! The problem is that you like Metallica, A7X, and Disturbed. The others are good (especially Rush). You might like music from Queens Of The Stone Age. Probably the album Songs for the Deaf. Another you may like is a gothic synthetic rock band called The Birthday Macre. They are not that big yet, but I'm sure they will be eventually. Pretty much everything they make is great. And last but not least is the band Killing Joke, who is in their fifties, just like Rush, but play like they're twenty. Hope that helps.
