The Cambridge Free Improvisation Society is an informal musical collective whose members are students at Cambridge University. We gather to freely improvise during sessions which are held on and off during Term times. We have performed occasional concerts and, for the past few months, have been recording the irregular jam sessions we hold in various college music rooms. Selections of these recordings are now being made available online, including 'Miracle of the Sun', an hour-long improvisation which will be available in CD-R form at gigs or on request. Feedback is welcome, and indeed encouraged.
