4444 OF A KIND Release Debut Single 'Waiting 4' on Tomorrowland Music

4444 OF A KIND, the live act formed by D-Block & S-te-Fan and Sub Zero Project, has released their debut single "Waiting 4" on Tomorrowland Music. The track merges the production styles of both hardstyle acts into a single hard dance identity.

Sub Zero Project's Decade-Long Run

Sub Zero Project, the Dutch hardstyle duo of Nigel Coppen and Thomas Velderman, launched in 2014 and built a catalog that includes "Darkest Hour," "Our Church," and "Trip To Mars," tracks that have accumulated tens of millions of streams. In 2023, they sold out Mitsubishi Electric Halle in Düsseldorf and Waagnatie in Antwerp. Their collaborations span artists like Timmy Trumpet and Hardwell, and in 2025 they released the single "It Will Be Ok" alongside a new live show titled "Our World."

D-Block & S-te-Fan's Two-Decade Legacy

D-Block & S-te-Fan have been active in hard dance for over 20 years. Albums such as Music Made Addictz and Antidote, along with tracks like "Angels & Demons" and "Ghost Stories," established their reputation for blending melody with hard dance energy. They marked their 20th anniversary in 2025 with a sold-out event.

Tomorrowland Performances Scheduled for July

4444 OF A KIND will perform on the Freedom Stage at Tomorrowland on Friday, July 17. Sub Zero Project has three additional sets scheduled at the festival: a back-to-back with Hardwell on July 17, a "Sub Zero Project & Friends" stage on July 19, and a Mainstage slot on July 25.
