Silversun Pickups - They're the new Smashing Pumpkins, literally. I thought they were them the first time I heard their song "Lazy Eye." They're really awesome so check them out.
Sick Puppies - A great new band from Australia. I don't know how to describe them, but they're great.
Lydia - They're an amazing ambient band, once again I can't really describe them, but their music relaxes me, but yet it gives me a rush to get up and do something with my life. So listen to them too!
