Chicago-born trailblazer Lee Foss continues his superb run of form on Repopulate Mars with a high-profile collaboration alongside GS5 on the three-track ‘Matter of Time’ EP, out November 28.

Title track 'Matter Of Time' marries grinding basslines and slinky percussion with a heart-wrenching vocal sample, while signature drums power onwards with a futuristic edge. Next up, 'WANNAGO' pairs sultry R&B vocals with a bumping groove – it's stripped back yet warm, and packed with romantic energy that will turn any dancefloor steamy. Closer 'Naivasha' is the most direct of the lot, with UK bass signifiers, old-school synth motifs, and low-end wobbles all worked into a driving groove. A pitched-up vocal adds an alluring Eastern twist to this fresh, distinctive sound.

“From the moment I started producing, Hot Creations and Repopulate Mars were two of the labels that shaped my taste and inspired my sound. Landing a release now on Repopulate Mars with Lee on this EP is genuinely a dream come true. It feels like a full-circle moment, and getting to collaborate with him on so much music this year has been both surreal and hugely motivating.” – GS5.

Lee Foss has always operated in his own sonic world — a place where house, tech, R&B vocals, and forward-thinking sound design collide. Heading up one of the most popular modern house labels of now, Lee Foss’ influence can be heard across clubs, charts, and radio waves worldwide. Since its founding in 2016, Repopulate Mars and its offshoots have unearthed and championed some of modern house music’s biggest stars, from Mau P to John Summit.

Fresh off his ‘So Hot’ collab with Gabss and XKYLAR, Foss now unites with fast-rising Denver staple GS5, whose BBC Radio 1 support and breakout sets at Experts Only and range have marked him as one to watch, for the three-track ‘Matter of Time’ EP.

Lee Foss & GS5 ‘Matter of Time’ EP drops via Repopulate Mars on 28th November 2025.
