The first release from Corbett vs. Dempsey drawing on the Paul Lytton Archives, this recording of electronic & acoustic improvisation from UK percussionist Paul Lytton and German guitarist Erhard Hirt was recorded in Belgium in 1981 for the German Po Torch label, founded in 1976 by Paul Lovens & Paul Lytton to release forward-looking forms of free improvisation.

A concert recording on the occasion of the 10th anniversary of Einstein Kultur in Munich from the quartet of Erhard Hirt on guitar & computer and Paul Lytton on drums, percussion & objects (half of the Quartet XPACT) plus Harri Sjostrom on soprano & sopranino saxophones and Philipp Wachsmann on violin & electronics, presenting a remarkable set of collective ea-improvisations.

Originally formed in 1985, this free improv ensemble continues in a new rendition of the Örchestrü, with original members Mark Charig (cornet), Paul Lytton (percussion), Alfred Zimmerlin (cello) and Phillipp Wachsmann (violin) joined by new members including Axel Dorner (trumpet), Phil Minton (voice), and Melvyn Poore (tuba), for two exceptional examples of advanced collective and cooperative improvisation.

The XPACT quarter of late saxophonist Wolfgang Fuchs, percussionist/electronics artist Paul Lytton, bassist Hans Schneider and electric guitarist Erhard Hirt came together in the mid-80s from members of M.A.I. Orchestra and Übü Örchestrü, disbanding after 4 years and now reunited 34 years later as a quartet with Stefan Keuene replacing Fuchs, releasing this album of masterful free improv.
