I-F (Interr-Ference) is the stage name of Ferenc E. van der Sluijs, a Dutch DJ, producer and broadcaster based in The Hague, active since the mid-1990s. His 1997 track "Space Invaders Are Smoking Grass" became a landmark underground hit widely credited with catalysing the electroclash movement. He runs the Viewlexx label and the 24/7 internet radio platform Intergalactic FM, and his mix album "Mixed Up In the Hague Vol. 1" (1999) is cited as a key catalyst for the Italo disco revival.
Viewlexx released the compilation 'Acid Bunker 2 - Directive 40' in February 2026, continuing the label's active release schedule.
Viewlexx issued two new releases in October 2025: 'Viewlexx V12/6 Love Explosion' and 'Viewlexx V12/19 Overkill'.
The Intergalactic FM Festival 2025 took place on 29 May 2025, featuring sets from artists on the Viewlexx roster.
I-F released 'Test Pilot Volume 1' as a digital release on Viewlexx in February 2025, with all tracks produced by I-F.
The Intergalactic FM Festival 2026 edition was announced for May 14-17 at PIP Den Haag, with early tickets selling out rapidly.
