Micheal David Larsen (November 9, 1981 – October 16, 2010), better known by his stage name Eyedea, was an American rapper, freestyle battle champion and songwriter from Saint Paul, Minnesota. He had appeared as a solo artist under the pseudonym Oliver Hart, and as the MC half of the duo Eyedea & Abilities (along with longtime friend and collaborator DJ Abilities). Larsen was first signed under Slug's independent hip-hop label Rhymesayers before founding his own record label "Crushkill Recordings". Eyedea's style of music is philosophical, abstract, political and poetic.
Eyedea first stepped into the hip-hop scene battling against other emcees at notable freestyle joints. His notable wins which included a victory at Scribble Jam (1999) and the televised Blaze Battle sponsored by HBO (2000), turned Eyedea into a hip-hop mogul.
