Jazz, defined by creativity, pushes boundaries — a fact alluded to and demonstrated by two of the new NEA Jazz Masters at the gratifying if lengthy ceremony and concert held at Rose Theater of Jazz at Lincoln Center on Tuesday, Jan 12. Muhal Richard Abrams and Yusef Lateef were inducted into the canon that now recognizes 114 musicians and advocates of what House Congressional Resolution 57 (passed with Senate concurrence in 1987) calls “a rare and valuable national American treasure.” Both men performed in ways that draw from but aren’t constrained by the heritage/legacy/tradition of swing, blues and ballads often cited by the conservative end of the music’s continuum as sine qua non for the four-letter, two-Z designation.
