The Green Apple Festival for Earth Day is throwing one of the best concerts of the Spring. The Roots, Thievery Corporation, Talib Kweli and so many more will be performing on the National Mall. There will also be guest speakers including Chevy Chase (yep, dude from Caddy Shack) and green tech exhibits. The best part about this celebration is that it's from 12 noon until 7pm, so you it will be the perfect time to pack a blanket, a salad and head down to the Mall. Oh yeah, and it’s FREE!
