Hailing from the Second Viennese School, composers Arnold Schoenberg and Anton Webern were lions of 20th century modernisms, championing serialism and a groundbreaking approach to harmony and dissonance. This Sunday, the Brad Lubman-led ensemble Musica Nova will interpret these twin titans of atonality at the Eastman School of Music. The student group will perform Schoenberg's Chamber Symphony No. 1 and Webern's "Five Pieces for Orchestra," as well as contemporary composer Dieter Mack's 2007 work, "Kammermusik V." Mack's stylistic approach is both sparse and evocative, resulting in music that is simultaneously beautiful and opaque. Mack will be present to conduct his work as a special guest; Vicky Shin will also conduct.
