Electric guitarist Olaf Rupp, one of the leading figures of Berlin's Echtzeit scene, and Rudi Fischerlehner, an active Berlin improvising drummer, have been playing together as Xenofox for years, releasing albums and playing festivals, here captured at A L'Arme Festival at Radialsystem, in Berlin in 2017 with turntablist Joke Lanz adding to their controlled chaos.

A unique merging of free improvisation and chamber jazz, the trio of UK bassist Paul Rogers with German guitarist Olaf Rupp and soprano saxophonist Frank Paul Schubert using stunning technique in sensible ways as they present three extended works, energetic yet never frenetic, stretching their concepts through tight and enthralling dialog, a great achievement.

The Berlin trio of Rudi Mahall on clarinet and bass clarinet, Olaf Rupp on electric and acoustic guitar and Jan Roder on double bass in an ironically packaged album of free improvisation of the highest standard, taking the listener on a journey of informed free jazz that references the past in thoroughly modern approaches to creative music.

The duo of electric guitarist Olaf Rupp and soprano saxophonist Christoph Gallio in a set of 13 studio improvisations, restrained and thoughtful dialog of great technical skill and unusual tonal approaches to both instruments.
