A friend of mine recently loaned me Carnavas, the debut album from Silversun Pickups. It's definitely worth a listen to anyone interested in rock; it's sweet and melodic for the most part, but carries a grungy edge that keeps things interesting. Songs are generally very textured, with a heavy 90's-alternative influence. Some notable tracks are 'Melatonin,' 'Lazy Eye,' and 'Checkered Floor.'  Check it out.
