Though only ever released in Japan and in sore need of reissue (affordability not being among the virtues of an original copy), Green Line sits easily alongside the most progressive jazz albums of the early 70s, many of which featured the work of the quartet’s alumni–namely Sharrock’s uncredited appearance on ‘Yesternow’ for Miles Davis’ A Tribute to Jack Johnson, Vitous’ early fusion-defining tenure with Weather Report, and Marcus’ collaboration with Japanese jazz-rock outfit Jiro Inagaki and Soul Media. And so, Green Line was ultimately the beginning and end of its own trajectory, but damn, what a glorious path it blazed.
