Main Phase is the stage name of Adam Emil Schierbeck, a Copenhagen-based DJ and electronic music producer from Denmark. Specializing in UK bass culture, his music blends garage, jungle, house, two-step, breaks, and dub techno, characterized by dark, atmospheric textures and heavy low-end frequencies. Schierbeck debuted as Main Phase in 2020 with releases on the UK label ec2a. He has since become a key figure in Denmark's underground electronic scene, contributing to the resurgence of garage and bass music in Europe. He co-founded ATW Records with Interplanetary Criminal and is part of the duo First Touch with producer Bjarke Bech. His productions, often hardware-based, emphasize syncopated rhythms and ambient dub influences.
