There's a growing feeling both inside and outside jazz that Kamasi Washington could well turn out to be one of the style's all-time greats. He's certainly making all the right moves, delivering thought-provoking concept albums of eyebrow-raising length that simply refuse to settle on one sound, rhythm, style or sub-genre. Heaven & Earth, his first album for almost three years, continues this trend, comprising angry instrumental answers to America's growing issues with class division and racism, Rotary Connection style workouts, Sun Ra-esque spiritual workouts, funk and soul-influenced burners, spiraling choral and orchestral affairs, and electric fusions of rubbery synth-funk and mind-altering jazz-blues. Typically, the results are never less than sublime, with Washington's virtuoso saxophone playing taking centre stage throughout.
