Micheal David Larsen (November 9, 1981 – October 16, 2010), better known by his stage name Eyedea, was an American musician, rapper and poet. He was a freestyle battle champion and songwriter from Saint Paul, Minnesota.
Larsen 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). He was first signed under Slug's independent hip-hop label Rhymesayers Entertainment before founding his own record label Crushkill Recordings.
Eyedea first stepped into the hip-hop scene battling against other emcees at notable freestyle competitions. Notable wins included a victory at Scribble Jam (1999) and the televised Blaze Battle sponsored by HBO (2000), which was hosted by KRS-One. Following the win, he won an impressive portion of money, but was also offered a higher cut if he signed a record contract with hip hop mogul P. Diddy, to which he denied, instead helping build Rhymesayers Entertainment from the ground up.
