My personal favorite Mike Patton! I love him!

Along with Greg Werckman, he co-founded and runs Ipecac Recordings. In May of 2006 he released his newest album "Peeping Tom" which is a collaboration of efforts from several other musicians. It is considered Mike Patton's version of a pop album, it took him several years to create/release. He performed live with Amon Tobin, a.o. at the 2005 Dour Festival.
Patton possesses a wide range of vocal textures and styles, ranging from falsettos, Sinatra-esque crooning and even death metal style grunts and screeches.
