As spring comes into full bloom, Alan Gilbert and the New York Philharmonic gear up for some colorfully-programmed concerts at home and on tour, showcasing a range of repertoire and some important guest artists. Among the many highlights of the remaining two months in Gilbert's third season as the orchestra's Music Director will be the world premiere of Composer-in-Residence Magnus Lindberg's Piano Concerto No. 2, a New York Philharmonic co-commission with the Royal Concertgebouw Orchestra and the Gothenburg Symphony Orchestra, with soloist Yefim Bronfman (May 3 -- 5); CALIFORNIA 2012, a six-city, seven-concert tour (May 8 -15) that includes the orchestra's debut at Walt Disney Concert Hall in LA (May 9); a continuation of "The Nielsen Project," the orchestra's ongoing survey of the six symphonies and three concertos of Carl Nielsen, with a performance of the Danish composer's Third Symphony, "Sinfonia Espansiva" (June 14 -- 16); and an all-Mozart season finale at Avery Fisher Hall, including one of the composer's most sublimely beautiful works: the Great Mass in C minor (June 20 -- 23). Two special concerts (June 29 and 30), co-presented by the Park Avenue Armory form Philharmonic 360 -- Spatial Music from Mozart's Don Giovanni to Stockhausen's Gruppen. Exploring the spatial qualities of the Armory's soaring, 55,000-square foot Wade Thompson Drill Hall, the program presents four iconic works in an unusual and illuminating setting in which the orchestra members surround the audience.
