There's been a concerted effort the last few years to address the gender imbalance in jazz, on the bandstand and in the studio but particularly in education. A lot of the heavy lifting in this ongoing process has been done by drummer Terri Lyne Carrington, and a major step forward is coming this month. Born in Massachusetts, Carrington studied at Berklee College of Music, after which she moved to New York, where she was affiliated with the M-BASE collective alongside saxophonists Steve Coleman and Greg Osby, among others, and then to Los Angeles, where she was the drummer for the Arsenio Hall Show band. She's released about 10 albums as a leader and appeared on dozens of others with artists including Herbie Hancock, Wayne Shorter, Diana Krall, Esperanza Spalding, Cassandra Wilson, George Duke, and more.
