Hank Mobley Quartet - s/t
Terrific 1955 debut Blue Note session of the 25-year-old Mobley (sax), Horace Silver (piano), Doug Watkins (bass), and Art Blakey (drums)...which may sound familiar, given the Jazz Messengers (which Mobley played with, too).
Old(ish) Music Matters 45 RPM re-release of 25 minutes of mono hard bop, mostly Mobley originals, save for Porter's Love for Sale.
