What are some good bands like At the Drive-in?

Couldn't agree more with the person above that suggested Mewithoutyou. If you were to listen to their first full length (A-B) Life and then their most recent release you'd be lost. They made a slow progression from a little more aggressive post-hardcore to an almost folky campfire, but still INCREDIBLE sound. Remains dark, but lyrical content is entirely different.

Suggestions from A-B Life:

Gentleman

Everything Was Beautiful and Nothing Hurt (one of my favorite songs)

Bullet to Binary

Nice and Blue

Well, since ATDI is a real emo band. Here's some others:

Sunny Day Real Estate

The Get Up Kids

Cap'N Jazz

Circle Takes the Square (interchangeable between emo/screamo)

Jawbreaker (interchangeable between punk / emo)

I love These Arms Are Snakes, they're a tiny bit similar to ATD-I.
