This trio set from three of New York’s most imaginative left-field musicians – Tim Berne drummer/vibraphonist Ches Smith, pianist Craig Taborn and tone-bending viola player Mat Maneri – displays such an unusual balance of compositional tautness (Smith wrote all the pieces) and spontaneity that assigning it to any jazz, improv or contemporary classical box is impossible. The nine-minute title track is typical, in the explicitness of the opening bell chime, Taborn’s show-and-hide chordal pulse, Maneri’s graceful ascents and a heated finale sprayed with brusque percussion rumbles. Cryptic viola melodies shadowed by rolling piano figures accelerate to frisky dances, stern tom-tom grooves stalk alongside intimate piano-viola dialogues, the fiddle equivalent of Jan Garbarek’s long sax outbreaths curl across dark landscapes before storms break. Smith’s vibes and Maneri’s viola share romantic exchanges that turn poundingly funky: Wacken Open Air has a sinister, monster-music relentlessness, For Days a catchy hook that dissolves into reverential slow-improv speculations. The UK isn’t yet on their impending world-tour schedule, but hopefully it soon will be.
