His current interests pivot around primitive electronics, generative methods, non-standard digital synthesis, and chaotic feedback systems.

His discography counts over two dozen releases ranging from underground tapes to acclaimed works such as Bats in the Attic (Pica Disk, 2010), a critic’s pick of The Wire in 2010 and his subsequent full length, Moon Over Torrelorca (Ljud & Bild Produktion, 2011), recorded on Serge and Buchla modular synthesizers at the EMS electronic music studio in Stockholm.

Keränen co-designed and implemented a generative, neural network-controlled sound installation together with Florian Hecker and Cerith Wyn Evans, which has been permanently installed in the Hijmans van der Bergh building of Utrecht University. He has also designed and implemented custom computer music tools and instruments for composers Lasse Marhaug, Sunn O)))’s Peter Rehberg, and Kevin Drumm, for The Hafler Trio’s performance/event ''''''' in Århus, Denmark, and for the Metsä exhibition by Santeri Touri at EMMA in Espoo, Finland. He has also collaborated with minimalist luminary Phill Niblock, among numerous other esteemed artists.

Keränen performs solo and with Norwegian noise duo Testicle Hazard, as well as the groups Gentle Evil, Les Manures, and The Truckfuckers.
