Mp3 of the Week: MC Exposition

DOWNLOAD: MC Exposition, "50 Million Pictures" (mp3)

MC Exposition does this strange thing when he performs: he rhymes so that people in the crowd can understand him. That’s one reason his organic hip-hop outfit, Audible Mainframe, was Boston’s most popular live rap group until it relocated to Long Beach last year. Expo’s clarity and timeless populist message might also explain why San Diego indie Wage Records recently re-released his 2003 solo debut, The Metro. It’s only right that Expo return home to resurrect cuts like “50 Million Pictures,” which finds him greeting old City Year friends, pulling tubes with UMass buddies, and grubbing New York Pizza. If you jumped on the Boston rap scene after the Audible train left town, or if you generally avoid rap shows on account of muffled, inaccessible vocals, Expo’s homecoming will be worth that last $50 in your account. Check him out along with the Greater Good, Awkward Landing, and special guests next Thursday, July 24, at the Middle East upstairs; and download “50 Million Pictures” above.
