Sounds like: Ratatat, Jay-Z & Notorious B.I.G, Ratatat, Slim Thug, T.I. & Bun B., RJD2
Ratatat have a very unique sound to say the least. Using a fusion of electronic beats and rock guitars and on occasion use samples to provide a theme throughout the tracks. Evan Mast's provides most of the twitchy beats (with the keyboards sounding like the machines that they were) and Mike Stroud's catchy riffs (with the guitar sounding like a synthesizer). - The Life Signs Project
