Ultimafestivalen, also known as Ultima Oslo Contemporary Music Festival, is a festival that focuses on contemporary music and artistic communication. The festival takes place from 11 to 20 September 2025, and aims to promote new music and artistic expression. In addition to concerts and performances, the festival offers podcasts and documentation of past events, helping to make the content available to a wider audience.
The festival has also launched a new membership program called ultiMATE, which gives members exclusive discounts and benefits. Ultimafestivalen is also involved in community outreach and artistic development, and offers opportunities for voluntary work and internships for those who wish to contribute to the festival's activities. This gives both locals and visitors a chance to participate actively in the festival's program and development.
