With momentarily records, he runs a boutique d.i.y. label that releases handmade and strictly limited-edition cassettes by international drone, ambient and experimental artists. he is a founding member of the instrumental black drone metal band [ B O L T ], which has an additional ongoing project called N + [ B O L T ].
In the past, Thomas Rosen made electronic music in the ambient and experimental genres under the stage name ninemiles – in a sense, rsn is the follow-up project to ninemiles, although both the musical style and the approach have evolved.
