O1

O1 is the solo project of Swedish producer Oskar Tobiasson. Launched in 2023, the project was created as a space for complete creative freedom after years of releasing music under his own name. Originally rooted in dark, minimal deep tech, O1 has evolved into a more melodic and expressive sound inspired by indie dance and timeless club music. In 2024, O1 began collaborating with producer Fabian Fouren, a partnership that has played a key role in shaping his artistic direction. After joining KOLLEQTIV in 2025, he met Gabriel Pascali, and together with Fouren and Süda they co-founded ŸUMA, a members club redefining Stockholm’s electronic music scene through community, creativity and culture. With multiple releases planned for 2026 and a debut album nearly two years in the making, O1 continues to build a sound that is constantly evolving while staying true to the dancefloor.
