The Canterbury Scratch Orchestra 

Improvised music.

The Canterbury Scratch Orchestra is a student collective
interested in an open approach to improvising music.
The orchestra’s previous performances have involved
responding to drawings, working with film-makers
and poets and collaborating with a diverse collection
of musicians including singer-song writers, Indian
classical musicians and laptop artists. The ensemble’s
work centres around people and play and at its heart
lies John Steven’s belief that music-making involves
‘practising an alternate society’.
