The debut album from Nik Bärtsch's Mobile was a recording made after a 36 hour Music Ritual at Blauer Saal, Zurich - a circumstance which created an acute degree of focus and intensity in this album, not quite found on any other album from the Mobile or Ronin output.

Offering a greater diversity of tone and colour than subsequent albums, Ritual Groove Music gives a clear picture of the "Ritual" elements within it, while at the same time allowing the players to move a little further in their improvisations from the ritual hub than they do in later recordings. This album also features the first appearance of "Modul 11", and fans may want to trace this track (alongside another favourite, "Modul 8") and its development throughout Nik's catalogue of superb recordings. A highly recommended introduction to the Nik Bärtsch groove.
