Jensen-Gerard Karp (born November 8, 1979), is an American writer, comedian, art dealer, producer, podcast host and former rapper raised in Calabasas, California
Karp was previously known by his stage name Hot Karl. Karl engaged in rap battling and freestyle at USC, during which time he took up the Hot Karl pseudonym.
Karp later entered the Roll Call freestyle competition on Los Angeles radio station Power 106, where he lasted a record 45 days on air to become the show's all-time champion. Karl created a demo exhibiting his satirical style and tightly-wound rhymes. He eventually signed with Interscope Records for almost a million dollars, where he recorded what was to be his debut album, Your Housekeeper Hates You, which included guest appearances by Redman, Kanye West, will.i.am, DJ Quik, Fabolous, Mýa, Sugar Ray, DJ Clue and MC Serch. However, Interscope informed Karl that his album could not be commercially released due to scheduling conflicts and he decided to leave Interscope. Jensen released his memoir, Kanye West Owes Me $300 (and other true stories from a white rapper who ALMOST made it big) detailing the entire experience in June 2016 with Crown Books.
Karl's music was featured in the video game NBA Live 2003, a game in which he was also a hidden character. His song, "Back/Forth," was also featured in the 2009 movie It's Complicated. Karl also appeared on season 2 of Burning Love on Yahoo & E! and battled Martin Starr as part of the show. He currently manages Nova Rockafeller, a Canadian rapper on Boardwalk/Mercury records.
