San Francisco’s renaissance folk ensemble The Lickets propose an interesting opportunity for a few dozen musicians — to perform Terry Riley’s “In C” as a group on Nov. 16 at Cafe Du Nord. More about “In C,” a composition of 53 phrases open to interpretation, from Wikipedia:

In C is a semi-aleatoric musical piece composed by Terry Riley in 1964 for any number of people, although he suggests “a group of about 35 is desired if possible but smaller or larger groups will work.” It is a response to the abstract academic serialist techniques used by composers in the mid-twentieth century and is often cited as the first minimalist composition.

Any instrument is welcome to participate, and one rehearsal will be coordinated before the performance. Interested persons should contact The Lickets via e-mail or MySpace.
