I need a new sound

Much like Huey Lewis needed a new drug in the 80s, I think I need a new sound. I grown kind of tired of the singer-songwriter thing, and the recent bands that are making it their business to rehash 80s music aren't really rehashing the thing I'm looking out for.
Not to say there hasn't been great music lately. Actually, there's been some fantastic stuff to come out in the last few years. Still, I'm waiting for the next Nirvana.
My ideal sound would be a mix of Buddy Holly and Otis Redding, with two or three part harmonies, too. So, I guess that would mean jangly, blues-based guitar structures, along with syncopated horns. Or something like that. It also needs to be quick, with a steady beat. With these features, at least the music will be upbeat; the lyrics can tell another story.
Overall, I think I want to take a break from moroseness in music. No more downbeat stuff.
Any ideas?
