Capturing the attention of Tiësto with his 2013 single "Gecko," Dutch electronic dance producer Oliver Heldens began his career with a handful of singles on the CR2 label in early 2013. This was a pivotal year for Heldens, and saw him remix Martin Garrix's smash hit "Animals" as well as release two 12"s for Spinnin' Records ("Stinger" and "Thumper"). Later that year, he teamed up with Oxygen Records and released "Onya" featuring Alvar and Millas. In the meantime, "Gecko" was picked up by major DJs and producers including Pete Tong, who named the track his "Essential New Tune" in January 2014. It also led to Tiësto releasing the track on his Musical Freedom label.

Heldens remixed Robin Thicke's "Feel Good" and made headline appearances at several of Europe's top EDM festivals that summer, including Tomorrowland and Creamfields. A vocal version of "Gecko" titled "Gecko (Overdrive)," featuring The Voice U.K. contestant Becky Hill, was released in June of 2014 and hit number one on the U.K. singles charts.

At the end of the year, Heldens had another Top Five hit in the U.K. with "Last Night (Koala)" featuring KStewart. Heldens ranked at number 34 on DJ Mag's Top 100 DJs of 2014 survey, and following his Essential Mix on BBC Radio 1, Tong named Heldens "one of the breakthrough producers of the year." In 2015, Heldens launched his Heldeep Records label with the single "Renegade Mastah" by HI-LO, which was later revealed to be a new Heldens project. Under his own name, he continued to release solo singles such as "Melody" and "Bunnydance," as well as collaborations with Da Hool, Zeds Dead, and Tiësto.
