1985: Run-D.M.C. became the first and only hip-hop crew to perform at the first ever Live Aid Charity Concert event held at Philadelphia's JFK Stadium on July 13, 1985. Today marks 33 years since they broke the hip-hop boundary.

Live Aid was organized by singers Bob Geldolf and Midge Ure to raise money for the fight against famine in Ethiopia. The concert happened in conjunction with a show at Wembley Stadium in London and was broadcast internationally across BBC, ABC, MTV and numerous radio stations. The global viewership of the event reacher 1.9 billion worldwide and it is estimated that donations from the first Live Aid concert in Philadelphia were around £50 million.

Performing in a lineup that included Bob Dylan, Madonna, The Beach Boys, Patti LaBelle and more, Run-D.M.C. performed a 10-minute set of two of their biggest hits to date, "Jam Master Jay" and "King of Rock" in front of 100,000 people. Not bad for some kids from Hollis, Queens.
