Robert DeLong mixes dance music with his own singer/songwriter style of craftsmanship. Utilizing MIDI interfaces and mixing live while he performs, DeLong plays keyboards, drum pads, drum set, laptops, and even gaming controllers to create his songs. Meanwhile, his lyrics and melodic sense often borrow from more classic pop influences. He made his debut on the Billboard dance charts with his first full-length release, 2013's Just Movement.
DeLong started playing drums at age ten and learning basic computer programming at 11. By high school, he was playing drums in pop-punk bands and experimenting with 3D animation. He started performing his innovative style of electronic music after moving to Los Angeles to study music at Azusa Pacific University. Glassnote released his debut solo album, Just Movement, in 2013. DeLong landed on the dance/electronic charts in the U.S. with both the album and the single "Global Concepts." A year later, he returned to the dance chart with the EP Long Way Down. Its title track reached the Top Three of Alternative Songs chart. In 2015, DeLong released his sophomore album, In the Cards, which crossed over to the rock albums chart. He spent much of the following year touring, including stops at Firefly Music Festival and Coachella, where he was joined on-stage by Kamasi Washington. Still with Glassnote, he returned in 2018 with the EP See You in the Future.
