Michael Tilson Thomas (MTT), being a fan of Bruce Hornsby’s recent modern, adventurous songwriting, asked Hornsby to appear as part of the New World Symphony’s 2015 “New Works” concerts. Hornsby performed four songs with the orchestra, and afterward MTT asked him to expand his program for future collaborations. Seven more new songs were scored for orchestra, and now this set of 11 pieces will be performed at Festival Miami with the Frost School’s Henry Mancini Institute Orchestra. Reflecting modern classical influences such as Olivier Messiaen’s “musique d’oiseaux,” Anton Webern’s pointillism, Elliott Carter’s late-career piano music, Arnold Schoenberg’s twelve-tone melodicism and Gyorgy Ligeti’s piano etude writing, this concert will include such songs (co-written with Hornsby’s songwriting partner Chip deMatteo) as “Life in the Psychotropics,” “Neighborhood Watch,” “Adonis,” and “Here We are Again.”
