Kummelholmen is an art gallery on the outskirts of Stockholm that has housed exhibitions by Lars Kleen and William Kentridge among others. It is a former hot water center with an oil cistern with an enormous reverberation. Swedish musicians Lars Almkvist, Bengt Berger och Martin Jonsson decided to see if we can make some slow music in it. So on June 11th in 2022 we climbed into it thru the very small hole dressed in protective overalls and improvised for an hour. Kummelholmen Sustain Session is the result, a suite with four parts and a short bonus track that actually was our first test of the accoustics. We think the result is worth your attention.
