Originally from St. Louis, Missouri, Robertson is a 1983 graduate of Hazelwood East High School. Students generally graduate in the year of their 18th birthday, which makes Robertson approximately 48 years old in 2013. He was the vocalist for a local electronic band called My Other Self in the 1990s and the owner of a record store called Deep Grooves.
Robertson later relocated to Los Angeles. While working a day job at Amoeba Records, he became well known in the local indie rock scene through his band, The Raymakers. During this time, he met Scott Schultz of the Orange County indie pop band Majestic, and they eventually played a couple of shows together. Years later, when Schultz was co-creating the show Yo Gabba Gabba!, Robertson was asked to serve as host.
In conjunction with appearing on Yo Gabba Gabba!, Robertson tours with The Aquabats performing kid-friendly DJ sets and dancing with the monster "cast" of the series.
