This morning I listened to the latest Skepticality [sic] podcast, Rationalist Rap. Swoopy interviewed Greydon Square, who is a hiphop artist, former gang member, former US soldier in Iraq and currently a physics student. I'm not a big hiphop fan, but I liked the mellow sound of his music and the poetry of his lyrics (in much the same way as I like the Hilltop Hoods, homegrown hiphop from the Adelaide Hills). Sometimes wisdom appears in unexpected shapes and forms.
Hear Greydon Square's music on his myspace page. I like 2008 A.D. and The CPT Theorem. Just a warning: as in most hiphop, some language may offend.
