In this episode, I try to get my head around sampling and copyright law with regard to music, and end up learning about one of the most sampled recordings of all time, 'The Amen Break', which for years has been uncredited by producers from hip hop to drum 'n bass. We are also gifted with new releases from wily guitar wizard John Frusciante - all for free, and far-removed from his work with Red Hot Chili Peppers. Lastly, we remember the watershed moment in art-punk trio Yeah Yeah Yeahs career, where silky synth anthems began to assert their dominance on 2009's It's Blitz!.
