Among successful mergers (of jazz and chamber music), we can now count the AnyWhen Ensemble, a quintet that Douglas Detrick brought together to perform his finely crafted compositions. AnyWhen creates nuanced, assured, work that combines the best of its sources. From jazz, the five musicians draw quick-witted flexibility and response—and swing, too, where indicated. At the same time, Detrick’s mature compositions elicit from his ensemble mates refined skills of technique and expression. Those provide the musicians with many resources—and perspectives—that are available to few jazz players.
