Liminal Spaces
(Confront)
Recorded live at Saint Augustine's Wrangthorn in Leeds, UK, the duo of saxophonist Ed Jones and drummer Emil Karlsen bridge free jazz and free improvisation in a dynamic, low-key but deeply interactive session, emphasizing collective phrasing, evolving structures, and subtle momentum in an hour-long exploration of nuanced, expressive dialog.

Nichunimu
Calados
(577 Records)
At the forefront of Chile's experimental improv scene, the Nichunimu trio of Benjamin Vergara on trumpet, Nicolas Carrasco on synthesizer and Matias Mardones on percussion are both lyrical in a style that adheres to traditional jazz of a relaxed unrushed intention, but warped through unusual rhythmic approaches and odd punctuations from synthetics and radio.
Cleaver, Gerald
The Process
(Positive Elevation / 577 Records)
Taking his cues from the electronic music of his Detroit roots, free jazz drummer Gerald Cleaver presents an album of synthetic rhythms and sonic landscapes, each piece composed in detailed arrangements of compelling and adventurous structures, from propulsive grooves to sinuous soundscapes, a surprising and exciting twist showing Cleaver's strong compositional skills.
Edwards, John / Emil Karlsen / Dominic Lash
Action Theory
(Spoonhunt)
A new take on the classic guitar, bass & drums trio line-up, bringing together three generations of improvising musicians--John Edwards on double bass, Emil Karlsen on drums and Dominic Lash, more typically a double bassist, here on a Telecaster electric guitar--in five studio recordings of great intensity and varying direction fueled by a minute attention to detail.
Butcher, John / Dominic Lash / Emil Karlsen
Here and How
(Bead)
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.
Sanders, Mark / Chris Mapp / Andrew Woodhead
CollapseUncollapse: Time in Images
(577 Records)
Starting as an electric jazz album, the UK trio of Mark Sanders on drums & percussion, Chris Mapp on bass & electronics and Andrew Woodhead on keys & electronics slip into moody and experimental ea-improv territory, fluctuating between acoustic and electronic material of masterful virtuosity, presenting two unconventional solo sections for drummer Sanders along the way.
Sanders, Mark / Emil Karlsen
Muted Language
(Bead)
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.
Light.Box + Emil Karlsen
The Undanced Dance
(Bead)
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.
Cleaver, Gerald / Brandon Lopez / Hprizm
In The Wilderness
(Positive Elevation / 577 Records)
Drawn from an experimental improv performance by drummer Gerald Cleaver and bassist Brandon Lopez at 577 Records' 2019 Forward Festival, electronic artist and producer Hprizm of the Antipop Consortium took those recording to reconstruct twelve works of illusory and often surreal music, from active beat-based electronica to hazy dreamlike ambience.
Spaces Unfolding (Metcalfe / Wachsmann / Karlsen)
The Way We Speak
(Bead)
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.
Bourne, Matthew / Emil Karlsen
The Embalmer
(Relative Pitch)

Durrant, Phil / Emil Karlsen
Grain
(Noumenon)
A wonderfully assertive acoustic dialog between London improviser Phil Durrant on mandolin and octave mandolin, and Norwegian percussionist living in Leeds, UK, Emil Karlsen, the two focusing on a quick flow of ideas that ebb and flow naturally, each complementing the other in tightly defined interactions, creating a consistent sound of rapid texture and impetus.
Archer, Martin
Anthropology Band [2 CDs]
(Discus)
Inspired by the music of 70's Miles Davis electric work, composer and saxophonist Martin Archer presents 15 compositions performed in two parallel sessions over two CDs, the first in a septet that includes Corey Mwamba, Pat Thomas and Dave Sturt, and the second an extended ensemble with brass and wind sections, each bringing distinctive life to these inspired compositions.
