“ “When I sent my music to deadmau5’s label and he chose to release it, people started assuming that my music was actually his side project… That response was such a big compliment to me… because Joel has always been a huge inspiration. But while it was fun for a bit, I suddenly thought about how I had to start being Jeff, so that I wasn’t being disrespectful to the brand that deadmau5 has built over the years.”
