nmo is a London-based freelance orchestra, which performs with a flexible playing strength (15 to 35 typically) dependent upon venue, occasion and the music being presented.

Though hardly still 'new' after 30 years (the orchestra was founded in 1977), the nmo has continued to redefine itself as the expectations of a modern instrument orchestra have developed. In the 1980s it was principally concerned, like many professional chamber orchestras, with presenting public performances in the main London concert halls (Queen Elizabeth Hall, St John's Smith Square) and elsewhere. Under its Principal Conductor, Clive Fairbairn, it received substantial acclaim in the national press, such as:

this extends also to rarer pieces by his contemporaries, such as Pokorny:
