“Bo Diddley remixed by Swizz Beatz” is how this New Zealander describes his music, which is awesome, as an idea. His debut doesn’t quite sound like that – Willy Moon’s a frail flower compared with Diddley, and his beats are pedestrian next to Swizz’s. But he’s on to something. His songs take the ferocity of early rock & roll, add hip-hop-flavored beats, ladle on some feedback – and move on before wearing out their welcome. You know “Yeah Yeah” from an iPod commercial; “My Girl” has a girl-group feel; “I Wanna Be Your Man” has a Buddy Holly vibe and deft barebones production. Moon looks like a fashion victim playing dress-up, but his music has smarts, and bite.
