Gustaff

Gustaff is a Spanish electronic music duo comprising Mark de Jong and Norman Lenden, who began releasing music in February 2019. The duo has also performed under the aliases Starr, Silk, and Sir Loungealot throughout their career. Since their debut, they have maintained consistent output with 27 releases spanning a seven-year period through March 2026.

Their sound centers on tech house and minimal deep tech, with forays into melodic house and techno. Gustaff releases primarily through Kubbo Records, Unnamed & Unknown, La Pera Records, Be One Records, and HardCutz Records. Their productions lean toward the deeper, more minimal side of tech house, avoiding the peak-time aggression in favor of groove-focused arrangements that work across different points in a DJ set. The duo's catalog demonstrates a consistent approach to underground tech house aesthetics while incorporating melodic elements that distinguish their releases within the minimal tech spectrum.
