Unfortunately the situation in Gaza is still terrible and inhuman. Enough reason to do another fundraiser even. Just like the earlier events: all profits will go to the good cause, it's the least we can do.
All money that's raised with this night will go to local projects via the Humaniti foundation.
Alteration brings a diversity of underground sounds that meet in the same spectrum. From UKG to Jungle/DnB, from Rave to Juke and Ghettohouse and all the waves beyond. Different sounds that are strongly connected, the perfect melange for a clubnight if you ask us!

Hailing from South Africa and based in Amsterdam, amz aims to bring the sounds of home to the main stage. Prioritising the femme sound, her musical ideology focuses more on sharing and storytelling than on traditional club mixing, pushing new and interesting voices and paying homage to the nostalgia we all know.
With her background firmly based in radio, amz takes her listeners on a journey of discovery, weaving together playful vocal forward tracks, with iconic hard-hitters, sure to get people singing along on the dance floor.

TMSV
TMSV has been a mainstay in bass music for more than 17 years. One of the Netherlands' most prolific underground artists, the catalog Tomas Roels has built over time proves his ability to produce a wide range of styles and genres within the bass music spectrum, earning him DJ and radio support from some of the most prominent names in underground electronic music.
He has built a reputation as an exciting, eclectic DJ as well. Not content with just playing 90 minutes of the same thing or mixing one banger into the next, he varies tempos and styles and isn't afraid to throw a curveball, even when he's only playing his own music. His chops behind the decks have brought him to Europe, the US and Canada to play clubs from Helsinki to Lisbon and from Seattle to Krakow, and festivals like Bass Coast, Shambhala, Outlook and Wildeburg. TMSV has been a Rinse FM resident since 2025.
