The motley crew (not Crüe) responsible for this disc stretch from Bourne, the English pianist and composer born in 1977, to Barre Phillips, born in San Francisco more than four decades earlier. Somewhere in between are Tony Buck, the Australian drummer best known for his work with The Necks, and Tony Bevan, the contemporary saxophonist responsible for bringing together this particular group. Right from the opening bars, it’s clear that they will draw on the familiar sounds of free jazz: unpitched saxophone breath, sandpaper percussion, plinky-plonky strings plucked inside piano lid or on limboing bass. The crucial test is whether worthwhile sentences can be formed from such vocabulary, and in the answer, happily, is yes: sentences that are sonorous and expressive if not necessarily entirely new. Given the diversity in age and background, it’s an impressively coherent sound too, bowed harmonic soon blurring into mouthpiece squeak.
