OM (Switzerland) has been played on NTS shows including Music To Ease Your Disease, with Sykia first played on 19 April 2015.

OM was a jazz rock band signed on the German ECM label in the 1970s. Formed in Lucerne, Switzerland, in 1972 and named after Coltrane's darkly convulsive album, the members of OM were initially inspired as much by the rock of Jimi Hendrix as by the new developments taking place in improvisation. "Electric jazz - free music" was their rallying cry, and they played it loudly. All in their early 20s when the group was launched, the members of OM achieved an early success at the Montreux Festival in 1974 which helped to put them on the map, and brought them to the attention of ECM. Four albums were recorded for ECM's sister label Japo, between 1975 and 1980: Kirikuki; Rautionaha; Om with Dom um Ramao; and Cerberus. In jazz rock's heyday, OM was one of the few bands who were approaching jazz from a rock direction, rather than vice versa: most of fusion's traffic took the opposite route. The validity of their approach is borne out by this compilation, with material chosen by the band. After OM broke up in 1982, its members continued to appear intermittently on ECM recordings, in combinations with each other and separately. Guitarist Doran, drummer Studer and bassist Burri all appeared on the album Musik für Zwei Kontrabässe, Elektrische Gitarre und Schlagzeug. Doran and Studer were also part of the power trio Red Twist and Tuned Arrow, and Studer was also in Pierre Favre's Singing Drums collective, and Rainer Brüninghaus's Continuum band with Markus Stockhausen. Saxophonist Urs Leimgruber has been away from ECM the longest - but also in his case there are some enduring connections: Urs today fronts a trio with bassist Barre Phillips and pianist Jacques Demierre, and plays regularly with Marilyn Crispell. He has become a major voice on the free improvisation scene. Indeed, all OM members have made their mark.
