Paliria

Boilerroom 16:00

Palíria is a Delft-based Dj from Greece. Sometimes he mixes hard groove vibes with bouncy beats while some other times hypnotic sounds are combined with trance elements in a complex interplay.

Showcasing a funky and tropical house set to start the day off with an energetic dance! That's what you can expect from the set of KAUD, two friends based in Rotterdam. On IOF, they will perform a set based on inspiration, from artists like Nu Genea to El Shab Arab.

Lov3less

Kafee stage 18:45

Dorpsstraat 3

Bartje Biertje is a true Delft local and has achieved great success. “Overdekte glijbaan” and “Waar is mijn fiets” are examples of the impressive body of work he has built up.

LE MOTAT, named after a moth, is the act for night owls. In a dark alley between Spinvis, Gorillaz, and André Hazes, he writes and produces indie bangers and tearjerkers. Poetic yet direct—not in French, but in the language of love: raw, honest, and always straight from the heart.
