$16 Rehearsals at Tanglewood, Lenox, Mass.
Every Saturday morning at 10:30, the world-renowned Boston Symphony Orchestra "rehearses" for their evening concert. Sure, the musicians wear T-shirts, not tuxes, and the action breaks as conductor Seiji Ozawa nudges the players as close to perfection as possible, but you can still expect a nearly flawless show. These guys aren't exactly putting on a high-school recital. bso.org
