‘A never-before-issued live recording of McCoy Tyner and Joe Henderson leading a stellar quartet with bassist Henry Grimes and drummer Jack DeJohnette at the hallowed lost jazz shrine Slugs’ Saloon in New York City in 1966. Recorded by the legendary engineer Orville O’Brien — behind classic 1960s jazz albums such as Freddie Hubbard’s The Night of the Cookers and Alice Coltrane’s Journey to Satchidananda — the tape has been in DeJohnette’s personal archives for nearly 60 years.’
