Rivers Cuomo is the front man for the uber-geeky band Weezer (one of my personal favorites). The current lineup consists of Scott Shriner (bass), Patrick Wilson (drums), Brian Bell (guitar), and Cuomo on lead vocals. The band's name derives from Cuomo's childhood nickname, given to him by his father.
Cuomo is a vegetarian and favors customized Warmoth Stratocasters. He is famous for being fan-friendly - chatting on the Weezer message boards as "Ace", inviting fans to play on stage with the band, and allowing fans to appear in music videos ("Beverly Hills, "Troublemaker", etc.). He is married to Kyoko Ito and the couple have a three year old daughter, Mia. Cuomo is a huge soccer fan - he supports the LA Galaxy here in the US, he is an avid Premier League watcher (favorite English team is Sheffeld Wednesday), and his favorite American player is Landon Donovan.

Weezer just released their eighth album, Hurley, on September 14th.
