Pianist Keith Jarrett suffered a massive stroke in February 2018, leaving him unable to play the piano. This date, recorded at Auditorium de l'Opéra National de Bordeaux on July 6, 2016, is his final French concert. It is the second release from his last European tour, following Munich 2016 (released in 2019) and The Budapest Concert (2020). All three showcase the improvising musician at a creative peak. The performance has been divided into 13 sections with natural breaks. "I" commences with an abrupt phrase that fades behind pedaled low notes. Jarrett is assertive, playing percussively distinct yet rapid single notes and shapes, while establishing a circular rhythm.

Michael Chapman is often cited as one of the unsung heroes of the British folk music community, but that tends to shortchange the eclecticism of his approach. While the melodic sense of British folk plays a large part in Chapman's music, one can also hear much of the "American Primitive" sound pioneered by John Fahey, and like Fahey in his later years, Chapman has a strong taste for experimental sounds, and all of these elements make themselves heard on The Polar Bear, the third in a series of free-form releases Chapman has recorded for Blast First Petite.

Bobby McFerrin is the debut album by Bobby McFerrin, released in 1982. Vocal virtuoso Bobby McFerrin ranks among the most distinctive and original singers in contemporary music – equally adept in jazz, pop, and classical settings, his octave-jumping trademark style, with its rhythmic inhalations and stop-on-a-dime shifts from falsetto to deep bass notes often sounds like the work of at least two or three singers at once, while at the same time sounding quite unlike anyone else.

Featuring Herb Robertson on trumpets, mutes & compositions, Frank Gratkowski on alto sax & clarinets, Julien Petit on tenor & bari saxes, Marcin Oles on double bass and Bartlomiej Brat Oles on drums. It is always great to hear the ever-inspired Oles brothers playing with the cream of improvisers like David Murray, Ken Vandermark, Chris Speed and Erik Friedlander…

Duval is joined by Herb Robertson, Bob Hovey & Jay Rosen on a very coherent & varied free jazz album. To justify the title, the four musicians play an incredible array of instruments, including bass, electronics, trumpet, whistles, voices, flute harp, trombone, foreign language, turntable, drums, percussion, bells, shark, and even an egg beater.

A major early release by tenorist Murray, 3D Family appeared originally on Hat Hut records as a double LP before eventually being re-released on disc by hat ART. Murray performs here in a live context with one of his very strongest rhythm sections: the intensely musical South African bassist Johnny Dyani and veteran master drummer Andrew Cyrille. The program consists of all Murray compositions, weaving between burners, funky dances, and soulful ballads…

These four segments are really one continuous free style improvisation between trumpeter Herb Robertson and drummer Phil Haynes, conveniently divided between pauses for listening purposes. There are extremes in dynamics and tempos, all of which are realistically captured by CIMP's unique engineering technique of recording unadulterated sound…
