On his first Blue Note date since relinquishing the Jazz Messengers moniker to Art Blakey, Horace Silver struck gold with the 1956 album, 6 Pieces of Silver, a sterling set of hard bop that introduced his indelible composition “Señor Blues.” The pianist was joined by an ace quintet featuring Donald Byrd, Hank Mobley, Doug Watkins, and Louis Hayes. Blue Note Classic Vinyl Series is all-analog, mastered by Kevin Gray from the original master tapes, and pressed on 180-gram vinyl at Optimal.
