In 2002, Pearl Jam guitarist Mike McCready went public with his two-decade struggle with Crohn’s disease – an inflammatory bowel condition that has no known cure. Since then, McCready has been one of the entertainment world’s leading advocates for Crohn’s patients, and for the eighth year in a row he’ll bring his side band Flight to Mars to the stage for a benefit concert for the Crohn’s and Colitis Foundation of America. Don’t expect to hear any Pearl Jam tunes tonight, though – Flight to Mars is strictly a UFO cover band, UFO being the English hard-rock/metal band that features Michael Schenker, one of McCready’s guitar heroes. Proceeds from the show will go to CCFA’s Camp Oasis, which provides support and activities for children living with Crohn’s and colitis. With Sweet Water. MICHAEL ALAN GOLDBERG
