Darryl McDaniels, also known as DMC from the pioneer rap duo "Run DMC", is undergoing surgery.
McDaniels had been complaining of pains in his left arm. His arm began to swell so bad that he was admitted to a hospital in New Jersey. Doctors discovered two artery clots. They are now performing a surgery to remove them.
McDaniels, 44, was scheduled to perform at a benefit concert this weekend.
McDaniels helped create the group Run DMC which featured him and his partner Joseph "Run" Simmons and Jason "Jam Master Jay" Mizell. Mizell was murdered in October 2002. Run DMC is credited with being responsible for introducing rap music into the mainstream, largely by keeping their lyrics clean and including rock-based riffs in some songs. Run DMC is also cited as responsible for starting the comeback of Aerosmith, who were shown in their cover song video for "Walk This Way".
Simmons has gone on to be now known as the Reverend Run. His family is featured on the MTV Show "Run's House", which showcases his family's life events and his off and on rap career.
In 2006 McDaniels was featured in an autobiographical VH1 show that told the story of his adoption titled "DMC: My Adoption Journey". He received a Congressional award for working with children for doing activities like opening up a summer camp for foster kids.
