Run DMC’s “Christmas In Hollis” was a landmark for hip-hop.

In 1979, at the age of 20, Kurtis Blow sold 400,000 copies of "Christmas Rappin." Blow would follow the record up with an even bigger record, "The Breaks."

Alicia Keys was only 16 years old when she recorded her version of "Little Drummer Boy" for Jermaine Dupri's 12 Soulful Nights Of Christmas compilation in 1996.
