Fifteen, the first album from the collective trio of saxophonist and flutist Henry Threadgill, pianist Vijay Iyer, and drummer and percussionist Dafnis Prieto, is the label debut for all three musicians. The record takes its name from the number of years the trio has been performing together - first at a series of benefits for the New York City club the Jazz Gallery, a club they have since played at periodically, and then around the US and internationally. It comprises three compositions by Threadgill and Iyer and two by Prieto.
