Rapper Greydon Square joins me again on the show to talk about his new album The CPT Theorem.

If you haven’t heard of 27 year-old Greydon before (or heard my first interview with him), his story is interesting: he grew up (as Eddie Collins) in a Group Home in Compton, California, got involved with a gang at a young age, was busted for a crime, and given the choice of prison or joining the US Army. He chose the latter and ended up in the US Army in 2001 and Iraq in 2004. During this time he was a committed Christian who studied the Bible. The more he studied the Bible the more questions he had about his religion which lead to his becoming an atheist, with many of the lyrics of his rap songs focus on atheism and the skeptic inquiry. He also is completing a physics major. His fans include Richard Dawkins, Penn Jillette… and yours truly.

This time, instead of focusing on his atheism, I wanted to talk to Greydon about how he writes his music. He’s a one man band – producer, composer, lyricist, performer, businessman. And, as you’ll here on the tracks I’ve laid into the interview, his shit is excellent.

You can buy his albums through iTunes or from the link on his MySpace.
