Organ jazz, which has deep roots in Philly, often veers close to R&B or hard bop. Tenor saxophonist Tom Tallitsch, a Cleveland native who has taught at the Philadelphia Clef Club, takes organ jazz in a cool modernist direction, making this quartet session smart and dark. Tallitsch, a jazz radio host on Mercer County Community College’s WWFM HD2, also runs a music-tutoring business in Princeton. Intimations of organ jazz’s soul roots emerge on “Tenderfoot,” but that becomes context for deeper explorations, fueled by drummer Mark Ferber. The set of originals often crackles with unexpected combustion. Organist Jared Gold creates some edgy effects on “Double Shot,” while guitarist Dave Allen plumbs a more cosmic mode on the smoky ballad “Perry’s Place.” Tallitsch & Co. sometimes play with sounds. The organ effects on “Dunes” feel like the Shore.
