Lincoln Center for the Performing Arts Tuesday unveiled its 1993-94 lineup encompassing $ 12 million worth of programming in six series under the umbrella title Lincoln Center Prods. Included in the schedule are works by composer John Corigliano, performances by dancer Bill T. Jones and the latest installment of the Mostly Mozart festival.“The scope of our organization’s programming has increased markedly over the past several years and the unifying identity of Lincoln Center Prods. is the logical result,” chairman George Weissman said. Nathan Leventhal, Lincoln Center prexy, detailed the schedule of more than 300 offerings supplementing the annual programs put on by the center’s 11 constituents, which include the New York Philharmonic, Juilliard School and the Metropolitan Opera. Jane Moss, programming VP, explained the focus of such ongoing series as Mostly Mozart Festival, Great Performers, Serious Fun!, Midsummer Night Swing and Lincoln Center Out-of-Doors. Mostly Mozart runs July 6-Aug. 21 with a weekly spotlight on another composer and his relationship with Mozart. An expanded commissioning program for composers extends beyond the season. Charles Wuorinen will compose a piano quintet. Other offerings on the schedule are Corigliano’s first string quartet (to be performed by the Cleveland Quartet); a dance by choreographer Garth Fagan with music written by pianist Don Pullen; and “Labyrinth,” a music and dance installation for Lincoln Center Out-of-Doors by composer Pauline Oliveros and choreographer Paula Josa-Jones. Rob Gibson, director of Jazz at Lincoln Center, said the third season of jazz will include 26 weekly National Public Radio broadcasts starting in April.
