TOTW: The Books_Smells Like Content

The Books music is made up mostly of a blend of traditional instrumentation and field recordings sampled and used in interesting ways.
I recently heard a breakdown of the track smells like content on the excellent podcast Song Exploder and was intrigued to find out how certain elements were made in the track especially the percussive pattern which was made by carving groves into the inside of a vinyl record which when looping creates the interesting rhythmic pattern.
