Collins, grew up in Compton, California, where he was raised as an orphan and became immersed in gang culture. In May 2001, he enlisted in the United States Army. He went on to serve in the Iraq War in March 2004. After returning from Iraq, Collins began attending college in Phoenix, Arizona as a physics major. It was at this time that he began questioning his prior religious beliefs and became an atheist, posting videos on YouTube. He has appeared in several television documentaries and radio shows, and his music has attracted fans such as Penn Jillette and Richard Dawkins.[1] He is also a member of the international secular hip-hop activist movement, The Anti-Injustice Movement (aka The AIM) and may be planning a UK tour.

Collins has been expressing himself through rap under his stage name of Greydon Square since 2001. Among his influences are Phil Collins, DJ Quik, Dr Dre, Quincy Jones, Stanley Clarke, Cedric Williams, and The Bee Gees. His first album, Absolute, was released in 2004 and is no longer available.

His follow-up album The Compton Effect, was released in 2007.  After being approached by several independent record labels and one major one, Collins created his own company to distribute the record.  In 2008, he released his next album titled The CPT Theorem. These two album titles provide references to the city of Compton (also called CPT) where he grew up, and to the Compton effect and the CPT Theorem from physics, which he studies.

The Kardashev Scale, set to release August 10th, 2010 is his 3rd studio album as Greydon Square.  It is a title comes from the Russian Scientist, Nikolai Kardashev, who In 1963 Kardashev upon examining cosmos came up with the idea that some galactic civilizations would be perhaps millions or billions of years ahead of us, and created the Kardashev classification scheme to rank such civilizations.  With the Kardashev Scale, Greydon employes creative samples from respected astrophysicists like Michio Kaku and Carl Sagan, a feature track with Canibus, and (19) new songs to add to his expanding catalogue of music. Greydon equates lyrical ability to the ancient practice of Martial Arts. Hip-hop is in everything you do, and your ability is not something to be taken lightly or shelved.
