Next?, in 1997–98 for the Berlin State Opera at the behest of conductor Daniel Barenboim. The work premiered in Berlin in 1999 and had its first staging in the United States at the Tanglewood Music Festival in 2006, conducted by James Levine. He later considered writing operas on the themes of communal suicide and a story by Henry James, but abandoned both ideas and resolved to write no more operas. Interventions for Piano and Orchestra received its premiere on December 5, 2008, by the BSO, conducted by James Levine and featuring the pianist Daniel Barenboim at Symphony Hall, Boston. On December 11, 2008, Barenboim reprised the work with the BSO at Carnegie Hall in New York in the presence of the composer on his 100th birthday. Carter was also present at the 2009 Aldeburgh Festival to hear the world premiere of his song cycle On Conversing with Paradise, based on Ezra Pound's Canto 81 and one of Pound's 'Notes' intended for later Cantos, and usually published at the end of the Cantos.
