The ALLOY Horn Quartet (LIZ DEITEMYER, ANNA JACOBSON, KELLY LANGENBERG, & DANA SHERMAN) is a fusion of artistry and advocacy whose appealing performances are powering their rise to the top of the chamber music scene. Equally comfortable in classical and contemporary genres, the quartet is at ease sharing its passion for music with audiences of all kinds. In addition to exceptional performing, Alloy offers charismatic dialogue to disarm the rigidity of a traditional classical music experience.

The quartet is a regular guest at concert series around the Midwest, including Indy Summers in the Park (IN), Chicago Brown Bag Lunch Series, and Richland Concert Association (IA). As guest artists at universities, Alloy is committed to facilitating dialogues about modern careers in music with workshops focused on expanding and creating meaningful work in the arts.


When not performing as a quartet, the hornists of ALLOY can be found in Chicago's freelance orchestral scene and performing with the region's top orchestras.  They have also played with well-known ensembles such as the Civic Orchestra of Chicago, Chicago Symphony Orchestra, Lyric Opera of Chicago, Chicago Philharmonic, Millar Brass Ensemble, Cleveland Orchestra, Elgin Symphony, Wisconsin Philharmonic, Arkansas Symphony, Omaha Symphony, and New Mexico Symphony.  Non-symphonic appearances include bookings for Peter Gabriel, Josh Groban, Video Games Live!, Il Volo, Mannheim Steamroller, Boston Brass, and others.
