WOW. Via a Pitchfork Media interview with Rivers:
Pitchfork: Can you elaborate on what a more experimental Weezer record might sound like?
RC: Longer songs, non-traditional song forms, different people writing and singing, instrument switching, TR-808s, synths, Southern rap, and baroque counterpoint– for starters.
When asked for clarification on the rapping part:
Pitchfork: Oh, and who’s doing the rapping?
