Trying to strike a balance between composition and the challenges of being a young parent, Rutger Zuydervelt, aka Machinefabriek, created a series of short tracks that could be developed quickly with invited collaborators, a concept that worked so well that in little time he found 52 enthusiastic and diverse musicians to develop the expanse of this impressive collection.

The 2nd release from the Bonjintan quartet led by Akira Sakata on saxophone, clarinet & voice, with Jim O'Rourke on double bass, Giovanni Di Domenico on piano & Hohner pianet, and Tatsuhisa Yamamoto on drums, an international grouping with experimental approaches to improvisation and avant music, yielding unusual results of great character, tension and pointed expression.

The 2nd album for this quartet, with Daniele Martini on saxophones, Giovanni di Domenico on piano, Goncalo Almeida on doublebass, and Joao Lobo on drums, for an album of slowly building free improv starting in a Necks mode and developing into frenetically lyrical passages, a great blend of modern and traditional approaches to free jazz.

Tetterapadequ, an anagram of "De Patter Quartet (but with a missing 'R') is named after the De Pater Jazz Club in The Netherlands where this collective improv quartet was born.
