You canu2019t go wrong with anything Miles did between 1963 and 1969, but my go to recording for this particular era is the Complete Miles Davis Quintet on Columbia from 1965u20131968. You really get to see how the band transitioned into fusion and itu2019s an engaging listen despite the 7-hour running time (albums collected in this set are ESP, Miles Smiles, Nefertiti, Sorcerer, Miles in the Sky, half of Filles de Kilimanjaro, and outtakes from the Water Babies and Circle in the Round compilations).A Love Supreme (Coltrane) is a perennial favorite and is my go-to if I want my sixties jazz a little freer, but also within the confines of a small ensemble. Plus, I rank it very high on my jazz albums list.Mingusu2022 Black Saint and the Sinner Lady is always a cathartic experience, but whenever I move back into jazz, itu2019s one of the first I pick up.Other favorites in continuous rotation are:Speak No Evil (Wayne Shorter)Go (Dexter Gordon)Rip Rig & Panic (Roland Kirk)Out to Lunch (Eric Dolphy)u2026.I give big amounts of credit to Sun Rau2019s Atlantis, Albert Ayleru2019s Spiritual Unity, Ornette Colemanu2019s Free Jazz, and Cecil Tayloru2019s Unit Structures, all masterpieces, but you have to be in the absolute right frame of mind and setting to listen to those. They require that much of your attentionu2026.and respect.
