A 6-CD box set in a magnetic snap case compiling double bassist Pascal Niggenkemper's musical journey between the years 2017-2022, in a variety of creative approaches improvising in acoustic and electroacoustic settings, from solo work through collaborations in trio, quartet and large ensembles; an absolutely magnificent presentation of his diverse work.

Creating complex intervals that the players must "notice among each other" as a model for coexistence, cellist Stefan Thut's score for three string players and sine waves, here configured for double bass (Félicie Bazelaire), acoustic guitar (Fredrik Rasten) and cello (Thut) with Léo Dupleix on sine waves tuned to multiples of prime numbers and attached to the wooden boxes that serve as transducers.

Two major works of evolving acoustic soundscape from Swiss violinist & composer Patricia Bosshard realized by the 27-member Orchestra des Nouvelles Creations, which includes Bosshard, Stephane Rives, Bertrand Denzler, &c.; "Sillon" employs a percussive pulse over 27 independently transforming grooves; "Reflets" a harmonic composition for bowed strings, including three double basses.

Rare and newly discovered works from jazz composer and pianist Mary Lou Williams performed by the Umlaut Big Band in their series of portraits of forgotten jazz artist, here taking a broad look at the prodigious career of this essential and gifted pianist, composer & arranger, whose influence on swing and early be-bop deserves this fitting and inclusive overview.

Four compositions for strings from German composer Hannes Lingens, including the three-part "Triptych" work performed by the Ensemble CoÔ, a septet directed by bassist Félicie Bazelair that emphasizes bowed strings; and two solo works performed by Bazelair: "Methods and Materials" & "Solo for String Instruments" employing advanced approaches to the double bass.

Created by Felicie Bazelaire, CoO is a string ensemble drawn from the French new music ensemble ONCEIM; CoO develops new repertoire for strings, collaborating with composers like Bertrand Denzler, who wrote this innovative composition "Arc" in two parts, a work applying unusual techniques to bowed strings, particularly lower bass tones, for fascinating results.
