David Willis, known by most as Ski and Ski Beatz, is an African-American record producer mainly working in hip hop. Discovered by DJ Clark Kent, Ski was originally known as "MC Will-Ski". In the 1980s, he was a member of the groups The Bizzie Boyz and Original Flavor.
As MC Will-Ski, he not only rhymed, but produced most of the tracks himself. After an extended absence from the hip-hop scene, "Will-Ski" re-emerged. This time strictly a producer using the shorter moniker "Ski."
Ski formed a partnership with Darrien Dash, cousin of Damon Dash. Together, they co-founded "Roc-A-Blok" productions, as a sister company to the then fledgling, Roc-A-Fella Records. Ski contributed four tracks to Jay-Z's debut album, Reasonable Doubt.
