2019.12.05, Anthony Tommasini (archive): Heartbeat Opera is far more unusual in its tweaking (and trimming) of librettos and its reorchestration of scores. ...the music director, Daniel Schlosberg, has effectively transformed Weber’s colorful score for seven players... Schlosberg has transformed the orchestration into a collage of electronic and acoustic sounds, in effect a recomposition... Heartbeat’s production team wanted to delve into the work’s disturbing, timely subtexts by streamlining and modernizing it. They succeed. ...By keeping the music in the original language and style, the contrast between American ambience and classic Romanticism made a powerful impact. Here was a rare presentation of the work that would define 19th-century German opera, made topical in a way that both respected Weber and stretched him.

I found the jazz-infused arrangement very insightful into the colorings and seductive allure of Bizet’s score. [Schlosberg] also played a mean accordion
2017.05.17, Mary von Aue (archive): In Mr. Schlosberg’s arrangement of the score for an intimate ensemble... the haunting melody of the “humming chorus” gives way to a dream sequence, assembled from scenes of Puccini’s Act I.

The Wall Street Journal
2019.12.09, Heidi Waleson (archive): the show’s most inventive elements are musical: Daniel Schlosberg’s lively arrangement for seven instrumentalists (most of whom double or triple), and the recomposition of the supernatural Wolf Canyon scene, for which Mr. Schlosberg and William Gardiner devised a creepy electronic soundscape of noises and wails that would do nicely for a horror movie. ...Mr. Schlosberg’s deft arrangement and his fine ensemble, which he led from the keyboard, supplied a lot of entertainment
