November 6, 2026 – “RE4SON,” out now via Tomorrowland Music, brings Hardwell together with 4444 OF A KIND, Sub Zero Project and D-Block & S-te-Fan. Hardwell and 4444 OF A KIND had already been discussing a collaboration when they headed into the studio to create something special for Tomorrowland. While working on the track, the artists discovered Kacie Jung’s singing videos on TikTok and reached out to her to record the vocals. Her voice brought the final piece of the collaboration into place.

“RE4SON” made its debut at Tomorrowland this summer, across Hardwell‘s and Sub Zero Project Project’s MainStage sets as well as the 4444 OF A KIND show on the Freedom stage. The full-circle moment came during Hardwell and Sub Zero Project’s back-to-back in The Great Library, when D-Block & S-te-Fan joined them on stage to perform the track together.
Two decades into his career, Breda-born Hardwell remains one of the defining names in electronic music. Voted the World’s No. 1 DJ in 2013 and 2014, he helped shape the sound of modern festival music with anthems such as “Spaceman” and “Apollo.” After a sabbatical, he returned at Ultra Music Festival Miami in 2022 with a darker, techno-driven sound, captured on his album “REBELS NEVER DIE.” His bond with Sub Zero Project runs deep, from studio sessions in 2023 to last year’s “Brace For Impact” with Lil Jon, while his radio show “Hardwell Presents Euphoria” airs exclusively on One World Radio.
4444 OF A KIND is the exclusive live act formed by D-Block & S-te-Fan and Sub Zero Project, built for pure dancefloor impact. The collective made its first statement earlier this year with singles “WAITING 4” and “4 THE RAVE” also released via Tomorrowland Music. Sub Zero Project, the Dutch duo of Nigel Coppen and Thomas Velderman, have taken the hard dance scene by storm since 2014 with anthems such as “Darkest Hour,” “Our Church,” “Halo” and “It Will Be Ok.” With a career spanning two decades, D-Block & S-te-Fan are synonymous with energy and melodies, from landmark albums “Music Made Addictz” and “Antidote” to their celebrated live act “Ghost Stories.”
“RE4SON” is out now on Tomorrowland Music.
