te.of Summer' inevitable hourly shuffle onstage between sets became a time for just about everyone to line up somewhere, whether it be for chicken and ribs at one of the understaffed refreshment stands or for an empty stall in the men's room. The wait for both items was mercilessly long, yet it seemd to bother few. Here was a chance to meet fellow jazz buffs, to talk about the music, the perfectly beautiful weather, or just about the long lines. MULTICOLORED BLANKETS and sleeping bags scaped a carpet on the lawn sur- rounding the amphitheatre. Festival-goers were allowed to bring anything they wished onto the grounds with one official exception-glass con- tainers. Late in the afternoon, when the temperature had cooled considerably, the air became thick with frisbees. At times, hundreds of the spinning plastic discs tinted the sky red, blue, yellow, and green, giving the grounds a carnival-like at- mosphere. The great musicians enjoyed their holiday from the dark nightclubs, too, gathering in small clumps in the backstage parking lot, mugging unabashedly for fans' cameras, and joking with admirers. In twilight, pianist Chick Corea and vibrahar- pist Gary Burton were treated to a tremendous ovation, performing duets with such closeness and skill that the two instruments frequently sounded meshed into one. One musician was able to catch falling crescendos where the other left off and lyrically raise them back up again like ocean waves. Burton and Corea, who are phenomena by themselves in their virtuosity over their instruments, created together one of the stunning mucical highlights of the daylong festival. The set climaxed with "La Fiesta," an untiring Spanish-style tune by Corea. Their ap- pearance, like therir list of recordings together, was all too short. Corea returned soon after with his new, 13- piece to ring ensemble to heat up the night chill. The pianist, wearing a boisterous flowered shirt picked up hileon a recent tour of Hawaii, direc- ted the unusual group through avariety of light numbers from his more recent albums. The en- he annual Newport Jazz Festival, where they were treated (lower left), the hard-driving saxophone of Sonny Rollins tra (below). ewarded generously by a steadily attentive udience. Charles Mingus was the subject of a 'ibute in the next act, which featured several of ie outspoken bassist's compositions performed y a specially-assembled All-Star orchestra. lthough Mingus, who is said to be very ill, was ot present, artists like Eddie Gomez, Pepper dams, Frank Foster, Slide Hampton and Mike nd Rancy Brecker supplied brilliant solo work. Much of the audience spent the afternoon >aming the grounds of the Performing Arts cen- r, letting the live music surround them like ool shade in the cloudless sunlight. The semble included a four-piece string section and an extra piano to complement the more conven- tional brass and rhythem sections. Featured on woodwinds was Corea's longtime accompanist and friend, Joe Farrell, with Gayle Moran ap- pearing as vocalist and pianist. The result was a beautiful, richly-balanced and jumping set. And when, in the middle of Corea's "Mad Hatter Rhapsody" pianist Herbie Hancock stepped in to duel musically with the leader, the performance practically took off. Only one act could have possibly topped the Corea ensemble. Jazz buffs gazed in awe as, one by one, a group assembled onstage composed of the super novas of the culture. The strange mix of jazz styles and idioms could never be forgotten once seen and heard this Saturday night: a sax line consisting of Sonny Rollins, Dexter Gordon and Mike Brecker, with Dizzy Gillespie and Randy Brecker on trumpet, Herbie Hancock on piano, George Benson and Larry Coryell on guitars, Jean-Luc Ponty on violin, drummers Roy Haynes and Tony Williams and vocalists Al Jarreau and DeeDee Bridgewater. To hear the entire group tear into Dizzy Gillespie's exotic be-bop classic "Night in Tunisia," listeners might have thought they wer in jazz heaven. The performance was simply un- paralled to anything ever heard before in jazz,
