The elder Glass promoted both new recordings and a wide selection of composers to his customers, sometimes convincing them to try something new by allowing them to return records they did not like. His store soon developed a reputation as Baltimore's leading source of modern music. Glass built a sizable record collection from the unsold records in his father's store, including modern classical music such as Hindemith, Bartók, Schoenberg, Shostakovich and Western classical music including Beethoven's string quartets and Schubert's B Piano Trio. Glass cites Schubert's work as a "big influence" growing up. In a 2011 interview, Glass stated that Franz Schubert—with whom he shares a birthday—is his favorite composer.
