Swiss accordionist Hans Hassler stands above the (small) crowd of improvising accordionist in the breadth of his career, his ability to balance both lyrical, abstract, serious, and humorous aspects in his approach to the instrument, a true original in intent and ability to engage his listeners, in 15 original and diverse compositions recorded in 2017.

One of the most active albums from the set of Lisbon String Trio (plus one) albums released in 2017, saxophonist Blaise Siwula brings a unique virtuosity to this live album from Galeria Monumental in Lisbon, prompting at times a chamber jazz feeling, alongside very free improvisation with impressive transitions from spacious to highly detailed playing.

Correctly configured, the Portugese ensemble Octopus is an octet, and though named after the most common of the breed, this 8-tentacled orchestration of strings, flute, trumpet, piano, guitar, electronics and percussion, all using extended techniques, slides deftly and with incredible restraint through a large, detailed dark-water work of electroacoustic improvisation.

A student of Christian Dierstein and Fred Frith, French percussionist Camille Emaille, working in both modern compositional and improvised music and influenced by Middle Eastern and Persian approaches, presents an album of solo percussion work selected from eight improvisations recorded in Bromont, Canada, using a diverse and unusual set of percussive instruments.

A beautiful album of darkly lyrical jazz duos from Israeli saxophonist and bass clarinetist Albert Beger and collaborator and member of the Albert Beger Quartet Shay Hazan, on double bass and guimbri, for seven pieces recorded in the studio: 6 improvised works and the composed piece "Cycles".

Three free improvisations from the Lisbon, Portugal trio of Jorge Nuno on electric guitar, Jose Lencastre on alto saxophone and Pedro Santo on drums, four pieces titled for the length of their dialog as they explore spacious sound sculpting and energetic free playing, a nicely balanced set of work that transition with finesse between ardor and tranquility.

Nine freely improvised introspections as "enlightening spots on different forms of life in a rather muddy environment" from Lucerne, Switzerland based tenor saxophonist Elio Amberg and pianist Christoph Baumann, wonderful miniatures of great style and skill, a diverse exploration of their fictional pond that's quite spellbinding and exciting.

Recording in Portugal, the quintet of Aural Terrains label leader Thanos Chrysakis on piano, Creative Sources label leader Ernesto Rodrigue on viola, son Guilherme Rodrigues on cello, Miguel Mira on double bass and Abdul Moimeme on electric guitar, three parts of microscopic collective electroacoustic improvisation of highly focused, detailed interplay.

Diverse aspects of the 2011 disaster at the Japanese Fukushima nuclear power plant brought on by a tsunami orchestrated in sound by composer/pianist Satoko Fujii and rendered in remarkable ways from some of New York finest improvisers, including Tony Malaby, Ellery Eskelin, Oscar Noriega, Herb Roberts, Joe Fiedler, Stomu Takeishi, Nels Cline, &c &c.

Double double bass from the duo of John Edwards and Olie Brice performing live at Iklectik Arts Lab, in London in 2017, a return of sorts as Brice's first live improv gig was opening for the Sunny Murray Trio with Edwards and Bevan; here the two combine, in contrast and confluence as they demonstrate massive technique and concentrative conversation.

Acoustic free improvisation with an ea-attitude, improvising drummer/percussionist Pedro Oliveira (Bernardo Sassetti) and classical pianist Paulo Mesquita used prepared instruments in a dialog that contrasts solid rhythmically melodic piano progressions with a mix of propulsive percussion, deep resonant tones, environmental timbre, and percussive interventions.

The improvising string duo of stalwart London improvisers, Daniel Thompson on acoustic guitar and Phil Durrant on the octave mandola, are heard in two settings of texturally rich, intricate interactions, first at Cafe OTO in 2022 for an extended improvisation, then at Cable Street Studios two months later for six succint, impressively diverse dialogs.
