Does anybody know any other bands like them? Like hardcore but not metal-core. Their one of my favorite bands but I barely listen to hardcore and I've heard bands like As I Lay Dying and others like them and didn't really like it.
mars volta, sparta, fall of troy... i think you mean post-hardcore and not hardcore.
There's already an At The Drive In thread. It shouldn't be that far back check the 3rd page. If not do a search. People will probably be able to help you more there.
