Early career
Born in 1981, Greydon Square, whose real name is Eddie Collins, began his musical journey while serving in the U.S. Army. His early exposure to online forums and the "atheist rap" community shaped his lyrical direction. He self-released his debut album, The Compton Effect, in 2007, establishing his trademark blend of complex rhyme schemes and cosmological themes from the outset.
Breakthrough
Greydon Square's breakthrough arrived with his 2009 sophomore album, The CPT Theorem. Released on his own imprint, GreyFive Entertainment, the project garnered critical acclaim within the underground and skeptic communities for its high-concept subject matter. While not achieving mainstream chart success, the album solidified his reputation as a formidable independent voice and expanded his fanbase significantly.
