Since 1978, Ochs's professional activities have been primarily centered around the Rova Saxophone Quartet, which has made over thirty European tours and numerous concerts throughout the U.S. and Canada, as well as recording over 30 CDs as a quartet and/or in collaboration with other artists.
Other performance groups:
In 1986, Ochs formed the group Room with Chris Brown and William Winant, a trio of saxophone, piano, computer electronics and percussion. The group continued performing and recording until 1994, and was one of the first bands to combine acoustic instruments and computer electronics in formal compositions that involved improvisation.
In 1990, he and keyboardist Wayne Horvitz formed The International Creative Music Orchestra for the Pan American Goodwill Games in Seattle with further performances at the Vancouver DuMaurier International Jazz Festival. In 1991, he suggested a collaboration between Room and The Glenn Spearman Trio, a sextet that eventually became an ongoing band, and recorded 4 CDs as Glenn Spearman Double Trio. In 1993, he created a nine-piece group to perform a specially commissioned work for Antwerpen '93 Festival entitled The Secret Magritte.
Also in 1993, he organized a saxophone octet (including the Rova quartet) to perform five compositions of his music at festivals in Austria and Germany. In 1994, Ochs joined with Lisle Ellis and Donald Robinson to form the ongoing trio, What We Live, which has toured in the US and Europe and recorded six CDs.
