Impeccably recorded in the studio, the long-running and varied collaborations of saxophonist John Butcher, double bassist Dominic Lash and drummer Emil Karlsen come together for the first time as a trio, recording eight succinct improvisations of remarkable technique and nearly telepathic dialog, allowing space for each player to display their masterful skill.

Steering far from pyrotechnics or histrionics, the drum duo of UK legend Mark Sanders and Norwegian residing in the UK and part of the new direction of Bead Records, Emil Karlsen, present six percussion improvisations that focus on textural interaction, melodic progression, polyrhythms, and sonic excitement through percussive elements; an exceptional duo.

The improvising duo light.box of Alex Bonney (trumpet) and Pierre Alexandre Tremblay (bass), using expansive electronic processing at the intersection of dark ambient, gestural improv and electronic environment, is expanded through the drums and percussion of Norwegian improviser Emil Karlsen, heard in these 2021 recordings at University of Huddersfield, UK.

All three having met in the London Improvisers Orchestra, Neil Metcalfe on flute and violinist Philipp Wachsmann each worked with drummer Emil Karlsen in separate projects including Tern, and then at Karlsen's suggestion creating this new Spaces Unfolding trio, heard in their first album, recording in the natural resonance of St. Mary's Old Church in Stoke Newington.

Two sessions from the free improvising electroacoustic trio of Philipp Wachsmann on violin & electronics, Martin Hakett on synthesizer and Emil Karlsen on drums & percussion, first for three studio recordings in 2019, and then in concert at the 2020 "Sounds Like This" festival at Leeds College for two wonderfully idiosyncratic and masterful conversations.

First meetings between British pianist Matthew Bourne and Norwegian drummer Emil Karlsen, two intrepid and like-minded improvisers using unusual techniques, preparations, inside playing and unusual percussive sources that fuel technically superb performances from both musicians, heard in six improvisations informed by masterful skill and creative drive.
