A set of lungs he has, this Canadian trumpeter, and a pair of lips strong enough to blast out the highest note a trumpet can hit, which is...well, who really knows? They just keep playing higher and higher. Among Bob Rice's projects is the group Primal Therapy, an ensemble that has dedicated itself to mastering the repertoire of Bill Chase, a trumpeter who led his band Chase on a chase through the jazz fusion era of the '70s, scoring a hit in 1971 with "Get It On." Chase chased high notes, of course, upping the ante by presenting a four trumpet front line, which is just exactly where Primal Therapy comes in. "These are the only guys on the planet that I know of that are crazy enough to even attempt to play the screaming trumpet music of Chase," a fan enthuses, capitalization and multiple exclamation points removed for the sake of sanity. "Upper-stratosphere ear-bleeding trumpet playing," he goes on, just in case one hasn't gotten the point yet. Rice is a music graduate of Humber College and is based out of Toronto, where he works regularly in a variety of styles including Latin, yet another excuse for high-note blowing.
