Just going to throw out three albums I think are pretty exceptional.
1) 65 Days of Static - The Fall of Math (2004) - download

They make like a collision of Mogwai and Explosions in the Sky, only more frantic sounding with some chalk-on-nails glitch stuff as well. Kind of scary and epic.
2)Ratatat - Classics (2006) - download

This album isn't even going to be released until sometime in August, I believe. It's better than their last album by bounds. Choice cuts are 'Loud Pipes' and 'Lex'. Sounds a bit like the Rapture, but with a little more funk-a-dunk.
3) Tokyo Police Club - A Lesson in Crime (2006) - download

Moderately spazzy indie-rock darlings. Lyrics you can sing along to for sure. It's just too short, really. A more garage/pop sounding Arcade Fire vibe.
If the download links don't work just let me know and I'll try and redo 'em.
