A tour-de-force of solo improvisation from French trombonist Christiane Bopp, flawlessly captured by sound engineer Jean Marc Foussat, as Bopp transforms her instrument through technical skill, lyrical ability, and unusual technique, creating virtual duets, furtive expression, and thundering emotion, an absolutely impressive example of modern trombone language.

A quartet of creative improvisers from Montreal--Joane Hetu (sax and voice), Pierre-Yves Martel (viola da gamba, harmonica), Emilie Mouchous (synth)--and from Germany--Carl Ludwig Hubsch (tuba)--blend conventional instruments with objects and profound techniques to create detailed and carefully controlled aural environments, enveloping the listener in rich, imaginative environments.

Prepared piano and percussion from Ofer Pelz and Preston Beebe, the percussionist using a diverse set of approaches to drums, cymbals and devices, blurring the sonic distinctions with Israeli-born Montreal-based pianist Ofer Pelz, whose preparations transform the piano in remarkable ways as the two focus on time, texture, space, and ambiance through seven fascinating improvisations.

A fun, odd and eccentric album constructed from extracts of hours of tape reels and audio cassettes by Montreal turntablist Martin Tetrault, a mix of plunderphonic sources, unusual turntable technique, and experimental audio collage drawn from an insanely diverse set of sources, in this sequel to his 1992 "Snipettes!" cassette, here with 31 new fascinating miniatures.

John Cage wrote his "Number Pieces" in the last years of his life, using his time bracket technique of short fragments allowing the performer flexibility in interpretation; each piece is titled for the number of performers and its ordinal position in the series, and most pieces are dedicated to a musician; here pianist Guy Vandromme performs three of the "One", or solo, series.

Two clarinetists--John McCowen, also the composer, and Madison Greenstone, both on clarinet & bass clarinet--taking the title from Boethius' (427-524 AD) printed work on ancient Greek music: "De institutione musica", as they generate long-form drones using the harmonic interactions and interference patterns of similar tones, overtones, and difference tones; impressively intense.

A beautiful rendering of French composer Eric Satie's 1918 masterwork "Socrate", originally for four sopranos and chamber orchestra, here stripped to its essence as a duo with Olalla Aleman on soprano and Guy Vandromme on piano, maintaining Satie's characterist reserve and refinement in the 3 parts: "portrait of socrates"; "banks of the ilissus"; and "death of socrates".

An adaptation from "Sileen", a composition commissioned by Musica For The Festival Oortreders at Neerpelt, Belgium, 2016 performed with 50 members of a local music school; "Sileen II" was realized with only Gareth Davis on bass clarinet plus sounds from Machinefabriek, recorded in the same pitch and tempo as "Sileen', then slowed to half its speed and one octave lower.

Reissuing the 1977 album from UK guitarist Ian Brighton, written as an instrumental story for children, apparently very sophisticated children, in a mix of composed and freely improvised passages, using non-idiomatic approaches with unusual and extended techniques, open atmospheric passages and strange transitions, a peculiar and wonderful album of imaginative playing.

Two saxophones take the front line in Paul Dunmall's 2018 studio album, the leader on tenor saxophone with fellow tenor player Julian Siegel, also on bass clarinet, while Mark Sanders drums and Percy Pursglove handles bass and also trumpet, as the band falls into a hard bop mode, weaving lines together over wonderfully turbulent and soulful grooves; outstanding.

A suite in seven parts named in Latin with abstract spiritual connotations from the Portuguese free improvising trio of Paulo Galao on clarinet & bass clarinet, Guilherme Rodrigues on cello, and Nuno Morao on percussion, each movement using subdued yet detailed and active motion, a confident and adept meditation of powerfully controlled communion.

Austrian violinist and composer Irene Kepl met French double bassist Fred Marty joined in the studio in France in 2018 to record this lively album of string interactions, both players showing masterful skills informed by classical and improvisational training, shown through impressive and mischievous technique and dialog that "Pirouettes", "Rolls", "Skids" and even takes a "U-Turn".

The Italian trio of saxophonist/clarinetist Francesco Masaro, pianist and prepared pianist Giovanni Cristino, and drummer/percussionist Walter Forestiere, take us on a journey at the lower levels of a forest's undergrowth, adding objects, preparations and extended techniques in a blend of free jazz and nonidiomatic forms to reveal mystery and brightness in the brambles.

Finnish guitarist Lauri Hyvarinen joins Portugues Creative Sources collective members Ernesto Rodrigues on viola, Abdul Moimeme on electric guitar, and Carlos Santos on synthesizer, for a studio album whose title refers to the shell of an object, a mysterious reference peeled away by this quartet through subliminal playing of intense technique and concentration.

Live recordings of the performance on March 1st, 2018 at the Galerie arToxin in Munich, presenting compositions from Udo Schindler performing on bass clarinet, soprano saxophone & euphonium, Gunter Pretzel on viola, and Georges-Emmanuel Schneider on violins & live electronics, three artists of diverse background crossing boundaries to create something unique and exciting.

A unique pairing of strings from Berlin improviser Wolfgang Schwabe performing on the Guqin, or Qin, a plucked seven-string Chinese musical instrument of the zither family, and Hui-Chun Lin on cello and voice, finding common ground in instant compositions of exotic string figures plucked and bowed, with Hui-Chun Lin sometimes adding emotional release in voice.

Taking two players from Guy Seger's Eclectic Maybe Band (Discus Records), classically trained Catherine Smet and improvising drummer Dirk Wachtelaer fulfill their album's title with 11 free dialogs, their dexterous mastery evident as they carry on energetic conversations of urgent activity, or lay back in cultivated discourse of sophisticated artistry; engaging.

Named for the city in which it was recorded, the trio of Karoline Leblanc on harpsichord, Ernesto Rodrigues on viola, and Paulo J Ferreira Lopes on gongs & cymbals, is a mysterious and ritualistic album, Lopes' gongs slowly intoning as the strings use unusual techniques, much of the harpsichord played inside; a subtle and beautiful reflection of historic Montreal.
