Frontliner is the stage name of Barry Drooger, a Dutch hardstyle producer and DJ from Amsterdam. He began producing in his early teens and first released music under the alias Abject before adopting the Frontliner name in the late 2000s. His work is associated with euphoric hardstyle, combining melodic lead lines, prominent kicks, and anthem-style arrangements. He has released original tracks, remixes, and event anthems, and his catalog includes widely circulated hardstyle tracks such as "Save.Exit.Planet" and "Call of the Visionary." Frontliner has also run the label Keep It Up Music and has been associated with the broader hardstyle scene through performances at major genre events, where his live sets typically center on high-energy festival and club hardstyle.
