Just got word that Jack Johnson is going back out on tour late this summer. I saw him last year opening up for Ben Harper, and have been wanting more ever since. I love that he's touring with G. Love and Special Sauce, who released Jack's song, Rodeo Clowns, as a single many moons ago. Can't wait to get tickets!
Another interesting combo is The Roots touring with 311 and Medeski, Martin & Wood on the 2004 Summer Unity Tour. I've been dying to see The Roots for a couple of years now, and it seemed like they just never seemed to play DC. Or maybe I was living under a rock the last time they were in town.
For info on these tours and more stuff coming to town this summer, check out the Summer Concert Guide. I'll be sure to post more gossip as I hear it.
