If you've not heard Kidcrash, they are a 'screamo' band from the states. Pretty much one of the only worthwhile bands doing this style of stuff recently. The guitars and drums are fooking of. the. chain. EVERYTHING is up to download there for free. They do, however, ask for a small donation if possible :)
If you are new to Kidcrash i'd download the split with l' antietam (another rad as band!), and then if you like that get the split with Coffin Dancer and the full length Jokes. They used to sound REALLY different. Like, awesome well produced / non screamy pop emo jam, basically. You can download that album at the bottom - New Ruins. Good fun!
