KEYBOARD SUMMIT/SOLO FLIGHTS. In a collaboration between the Kitchen and Composers Collaborative, seven pianists who specialize in new music have joined forces for an ambitious two-week overview of contemporary keyboard works. The centerpiece of the series is ''The Road,'' an eight-hour work by Frederic Rzewski that he describes as a novel for the piano. Mr. Rzewski, a formidable pianist, has been playing sections of the work sequentially during the series. Now it has reached the home stretch: he plays Part 6 tonight, Part 7 tomorrow and Part 8 on Sunday. Before Mr. Rzewski's performances, three other pianists will play sets of their own. Guy Livingston, who has commissioned composers of all stripes to write 60-second works for him, is to play a sampling of them tonight. Eleanor Sandresky is to perform her own ''Dream Journal'' tomorrow. And Jed Distler is to perform ''110 for 911,'' a work for a speaking pianist and electronics, with a text that includes contributions from 110 poets. Tonight and tomorrow night at 7 (Mr. Livingston and Ms. Sandresky) and 9 (Mr. Rzewski), and Sunday at 4 p.m. (Mr. Distler) and 6 p.m. (Mr. Rzewski), at West Park Presbyterian Church, 165 West 86th Street, Manhattan, (212) 663-1967. Tickets: $18 in advance, $20 at the door ([Allan Kozinn]). NEW YORK CITY BALLET. Catch new dancers in familiar pieces this weekend. Tonight's performance features role debuts by Janie Taylor, Alexandra Ansanelli, Sebastien Marcovici and Jared Angle in Peter Martins's ''Reliquary,'' and by James Fayette, Robert Tewsley and Arch Higgins in George Balanchine's ''Vienna Waltzes,'' whose cast also includes Kyra Nichols leading the sumptuous, bittersweet finale. Tomorrow night, new roles will be danced by Sarah Ricard and Mr. Angle in Jerome Robbins's ''Interplay,'' and by Mr. Marcovici, Carla Korbes, Ms. Taylor and Ms. Ansanelli in Mr. Martins's ''Sinfonia.'' And on Sunday afternoon, the presumably tireless young Mr. Angle will lead the first movement of Balanchine's ''Symphony in C'' for the first time with the veteran Abi Stafford. Tonight at 8; tomorrow at 2 and 8 p.m.; Sunday at 3 p.m. New York State Theater, Lincoln Center, (212) 870-5570 or www.nycballet.com.
