Some albums are so much of their time that they serve as historical documents just as much as musical recordings. Following John Coltrane's death in 1967, the promise of his journey into spiritually charged free jazz was enthusiastically taken up by the so-called ‘second wave’ of free jazz musicians – younger African-American artists fired up by political turmoil and racial tensions in the US. Tenorman Frank Wright stood right at the vanguard of that movement, and One For John – dedicated to Coltrane – is the quintessential session. The title track, taking up all of side one, seethes with revolutionary fervor as Wright peels off into scorching post-Ayler altissimo and ululating vocal glossolalia, over plunging piano chords, raging drums and Noah Howard's sizzling alto. The flipside's ‘China’ is a little more problematic, opening with an ersatz oriental piano motif that lacks 21st century sensitivity – but when the energy kicks in, it's another glorious blast.
