In August, 2011, the town of Piaggine, Italy, in the province of Salerno, honored Nicolas Flagello and his brother Ezio, a world-famous operatic bass-baritone, among other distinguished individuals who trace their ancestry to this town. The event culminated in a concert, the inauguration of a museum, and the re-naming of a street in the town after the brothers. Read more about this event.
In 2013 Naxos released an important new recording featuring Flagello's Odyssey, Symphony No. 2, Concerto Sinfonico (as transcribed for band by M. Patterson), and Valse Noire (as transcribed for saxophone quartet by W. Simmons). The recording features the University of Houston Wind Ensemble, conducted by David Bertman, along with the University’s saxophone quartet. Fanfare's Phillip Scott wrote, "The music is first-rate and the performances are excellent.... one of the very best releases in the Naxos Wind Band Classics series, and a welcome addition to the growing Flagello discography."On October 9, 2015, Bertman will again perform the Symphony No. 2 with the University of Houston Wind Ensemble.
