Anthony is hanging out at Zack's when it suddenly starts to rain. Zack decides to get out one of his USB sticks and put a bunch of his favorite mixes by Generation Trance (GT), on it for when Anthony goes back home.
This is actually a little homage to Zack's origins. I initially created him as a big time DJ and fan of another, named GT, and his favorite mix from them was Voices of Summer 2004. His current incarnation continues that tradition but has been scaled back to a internet radio DJ instead. In real life, I'm a huge fan of GT, and wanted to express that through Zack, then known as Z, when I first created him.
