The Books - Smells Like Content
Before The Books broke up, they released four albums that combined composed music and found sounds. In this episode, Nick Zammuto explains how he crafted the song Smells Like Content, off of their 2005 album Lost and Safe, out of unlikely sources, like geometry, chance encounters, and a corrugated PVC pipe.
