One of techno's true underground heroes, Function (Dave Sumner) has been DJing and making music for over 25 years. He is a founding member of the Sandwell District collective, Ostgut recording artist and owner of Infrastructure. Hailing from New York, he was seduced by techno when Jeff Mills held residency (as well as his own first) at Limelight in the early 90s. Producing from the mid-90s onward, he released his first 12"s on Damon Wild's Synewave and his own Infrastructure imprint. In 2017, he celebrated nearly 25 years as a recording artist, releasing a retrospective compilation for the newly formed Ostgut Ton off-shoot; A-Ton.

Alongside an already eventful year, Function engaged in a new project which would form the techno supergroup LSD in collaboration with Luke Slater and Steve Bicknell that they would described as "lysergic machine music". The trio debuted on Ostgut Ton with a 3 track EP titled "Process", too much acclaim, in conjunction with mesmerising performances at both ADE and Berghain. 2019 will see Function re-inventing himself once again: releasing a fresh batch of newly orchestrated productions in the near future and roaring with energy to get back on the road playing shows. As always, Function keeps on shifting to the next gear and will no doubt be turning a lot of heads in the years to come.
