-Coheed and Cambria would be a great band to look at. They've blended pop-punk, metal and prog and come out with a really original sound.
-CKY are another recent band that's taken familiar formulas and done their own thing, using unique riffs and guitar sounds to get something that again can't be placed in one genre.
-Smashing Pumpkins aren't quite the last ten years, but they were around for five of them. They took Nirvana-style chord grunge and mixed it with spacey alt rock and again were left with a new sound.

The first two of these bands aren't exactly mainstream at the moment, but they're quite well known, and have definately found their own style. Oh, and they just happen to be three of my favourite bands ever
