Hailed at his death in 2017 as the jazzpapst, the pope of German jazz, pianist Michael Naura once fronted the most popular post-bop jazz combo in early 60s Germany. After a serious illness brought his performing career to a halt, he took over editorial management of the state radio NDR’s jazz programming in 1971. There Naura had a front-row seat to the birth of fusion. Soon after, he returned to the studio at the head of a newly assembled electric jazz quartet. Their first release, Call, is a moody, shimmering wash of jeweled tones that sounded like nothing else in European jazz.
