I he vibraní, rougn-hewn music oí New urleuns' parade and dance hands lias served as lia' great wellspring of American popular tnusic (fed by the country blues) tor alinost a hundred years, muco Afro-American musicians first hepan afoiming European musical technology with the spirit and intelligence of commuñal África. At lirst strictly a functional music played tor the traditional funeral and celebretory parades and lor dancing, in a time before radio, records, televisión and film existed as mass entertainment media, the classic music of New Orleans has retained much of its original musical vitality vvhile passing from the streets and dancehalls to the concert stage as a "preserved" folkloric art form. The Preservación Hall Jazz Band, presented at Music Hall Mareta I4th to an enthusiastic capacity crowd, brought Detroiters a sweet taste of oíd New Orleans and its world-shattering musical genius, embodied in the persons of pianist Sing Miller, clarinetist Willie Humphrey, lus brother Percy on trumpet, 84-year-old Jim Robinson on trombone, the great Cie Frazier, drums, and Preservation Hall proprie tor-t ubaisl Alian Jaffe. Their music, formulated in the lirst quarter of this century, proposes all the major directions in which jazz has developed since: from eollective improvisaron to the pre-eminence of the soloist, trom small-group looseness to bigband tightness (the classical jazz orehestra is simply an elaboration of the reed-trumpet-trombone-rhythin combination introduced by the New Orleans players), from solo piano to piano trio to piano as the rhythmic and harmonie foundation of the horn-dominated band. The mind reels with illuminations as the underpinnings of all popular music in America are carefully and w4ttily drawn, laid out, and elaborated upon by these sly old survivors of the jazz wars! May they live forever! Once again, our highest compliments-and thanks-to the good people at Music Hall. whose jazz series, like almost everything else they present, has proved a resounding success. Please keep them coming-harder, taster, and ever more various. Detroit is ready fot it!
