I really like Kill Hannah and Shapes of Race Cars.
Kill Hannah it seems is always compared to Smashing Pumpkins, but I find them a lot more similar to STG...a little gothier though.
Wow, okay, I know I'm super late in responding to this, but it took me a while to really notice Kill Hannah even though I had a song or two of theirs. I really like them too, though I actually think they sound similar to Silversun Pickups. Mostly due to his singing voice as it has the strangely soft, raspiness.
