Both Trey Anastasio and Mike Gordon are using the popular social networking/stalking site MySpace to offer some new tracks. Anastasio is currently streaming ‘Sidewalks of San Francisco,’ from his new album _ The Horseshoe Curve_ and a 13-minute live version of ‘Burlap Sack and Pumps,’ from his new EP, The Lucius Beebe EP. The latter song also features special guest John Medeski on keyboards. Likewise, Gordon is now offering his previously unreleased demo of Simple from his days playing in Phish. Neither musician currently has any shows scheduled, but the pairs former bandmate, and Top MySpace friend, Page McConnell will play Portland, ORs Aladdin Theater tonight.
