There was a nice little article in Friday's Chicago Tribune on Justin Roberts' approach to preparing for a concert. Since he often sings in the morning, he "relies heavily on caffeine, starting his morning with a bowl of cereal with soy milk and several shots of espresso," a pre-concert routine that is, I suspect, not that of a typical rocker's.
The article notes that he's currently recording songs for his next album, Meltdown!, for an early 2006 release.
