Former XXL Freshman Macklemore is having a year most rappers can only dream of, sending three singles ("Thrift Shop," "Can't Hold Us," "Strange Love") onto the Top 20 of the Billboard Hot 100, including two No. 1′s. And, as recently announced, he and partner Ryan Lewis will be performing at this year's MTV VMA awards and have the chance to take home up to six moon men. Yesterday, Mack and Lew added to this year's wild ride by performing on Good Morning America's Summer Concert Series in New York City's Central Park. Turn down for what?
