This twelfth volume of the Annual Review celebrates the fiftieth anniversary of the Institute of Jazz Studies and features articles covering subjects which have not been engaged in past issues of the Review. Gil Evans, Django Reinhardt, Lucky Thompson, and Paul Bley each receive much deserved critical attention in this issue. This issue also includes a photo gallery illustrating some of the prominant locations and people of the Institute's history, both in New York and at its present home at Rutgers in Newark, New Jersey.
