BBE latest "deep dive" into a widely underappreciated style focuses on a particularly fertile period in the history of Japan's "contemporary jazz" scene. Curated by renowned Japanese jazz diggers Tony Higgins and Mike Peden, J-Jazz focuses on material recorded and released between 1969 and '84, a period the label says represents a "golden age" for jazz in Japan. Predictably, the compilation is both a serious history lesson and hugely enjoyable to listen to, featuring a mixture of U.S-influenced jazz-funk, fusion, post-modal and deep, spiritual improvisations. Naturally, all of the material has never been released outside of Japan before, with the vast majority of tracks being either ludicrously rare or sought-after. Simply essential, all told.
