This episode of POP THEORY is a VERY special one as Zach is joined by the absolutely brilliant ZEE MACHINE.  Together we take a dive into their discography, talking about songs like "The Radio," "Better Off" and his upcoming single "Worse" which is out May 9th!  We also get the opportunity to talk about his creative process, their current TEARS & GEARZ TOUR with Bentley Robles and some of the incredible artists that would keep him sane if stranded on a deserted island.
