Trained as a music historian, Shawn Marie Keener is an editor, indexer, and graphic designer based in Chicago.

Debra Nagy
Debra Nagy has been called a “musical polymath” (San Francisco Classical Voice) for her accomplished performances as a singer and historical wind player. She is the founder of the Cleveland-based ensemble Les Délices and plays principal oboe with Boston’s Handel & Haydn Society, Apollo’s Fire, and many other ensembles. Inspired by a creative process that brings together research, composition in historical styles, improvisation, and artistic collaboration, Debra creates programs that “can’t help but getting one listening and thinking in fresh ways” (SAN FRANCISCO CLASSICAL VOICE). During the pandemic, Debra reimagined Les Délices’ traditional concert series for the virtual space and created an acclaimed webseries variety show called SalonEra. Other recent projects have included critically-acclaimed multimedia productions of Machaut's medieval masterpiece Remede de Fortune, music from the Leuven Songbook (c. 1470), and an acclaimed CD combining jazz and French Baroque airs called Songs without Words, and The White Cat, a pastiche Baroque opera for singers and chamber ensemble with puppetry and projections based on the Countess D’Aulnoy’s 1690s feminist fairytale. She has recorded over 30 CDs with repertoire ranging from 1300-1800 on the Chandos, Avie, CPO, Capstone, Bright Angel, Naxos, and ATMA labels, and has had live performances featured on CBC Radio Canada, Klara (Belgium), NPR’s Performance Today, WQXR (New York City) and WGBH Boston. www.debranagy.com
