"Untitled" is an original composition by David Santoro, a bassist and educator on the faculty at Berklee College of Music. The piece appears on tenor saxophonist Sam Dillon's 2018 album Out in the Open, where it is performed by a quartet featuring Dillon on tenor saxophone, Peter Zak on piano, Yoshi Waki on acoustic bass, and Billy Drummond on drums. Santoro's connection to the recording likely stems from the close-knit circles of the New York and Boston jazz scenes, where working musicians and educators frequently contribute material to one another's projects. The title itself, "Untitled," suggests either a deliberate choice to leave the composition unnamed or a working title that was never replaced, a practice not uncommon among jazz composers who prioritize the music over its labeling. Little published information exists about the piece, and it does not appear in standard jazz repertoire lists or major discographies beyond this recording. As an obscure original written by a respected but relatively unpublicized composer, it represents the kind of fresh material that working jazz musicians regularly seek out to distinguish their recordings from more familiar repertoire.
