Music career

2011–12: First releases

In 2011, at the age of 20, he vacationed in Sweden, where he discovered electronic dance music. After returning to college he started producing mashups, "mainly because [he] didn't think anyone was doing a good job." He soon began mixing under the professional name 3LAU, and by June of that year was uploading mashups to YouTube.

3LAU gained recognition in the electronic music world in 2011 with his two bootlegs, "Girls Who Save the World" and "All Night Long". He additionally won a remix competition for his remix of Tiesto's "Work Hard, Play Hard".

Before 2012, 3LAU spent his days studying at Washington University in St. Louis and DJing at night. He has had remixes charts in the top 10 on both Beatport and Hype Machine.

2012–15: Singles, touring

In 2012, he focused on DJing and launched his 3LAU Your Mind tour. That same year, he released his second bootleg album, Dance Floor Filth. In 2012, the Las Vegas Review-Journal described him as "one of America's fastest-rising DJ-producers." In 2012 he released Dance Floor Filth 2, an album featuring his production.

In late 2013, he went on a short tour with Carnage called the Night Riot tour. Wrote Jonah Ollman of Sound of Boston about 3LAU's live performances in late 2013, "A nice balance of mashups, electro-house, poppy vocal samples, and a 90’s throwback here and there keep the young 20-something crowd going and constantly entertained."

In the summer of 2015, 3LAU did his first European tour visiting Barcelona, Germany and Ibiza. Later that fall, he went on his first Asian tour which included Bangkok, Jakarta, Tokyo and more.

Style and equipment

Much of 3LAU's music incorporates electro house, dubstep and progressive house. He is known for his melodic take on dance music and live sets that incorporate sampling. He is additionally known for using Ableton.
