The versatile drummer Michele Rabbia is a purveyor of both airily crisp-toned grooves and a painterly percussive soundscape, and has collaborated with everyone from Roscoe Mitchell through to Paulo Fresu. His Italian colleague Gianluca Petrella is a gifted trombonist and regular sideman of Enrico Rava, while the innovative Nordic ambient jazz-rock guitarist Eivind Aarset needs no introduction. On Lost River they find common ground in finely detailed yet organic ambient-sonic transformations The recording could easily double as a soundtrack to a documentary filmed in outer space. The hint of a lifeform arises in Petrella's hazy minimalistic trombone lines -though he's disappointingly underused in the set as a whole. Standouts include Aarset's gentle trickle of chords on the woozy ‘On What Floats Beneath’ and ‘Night Sea Journey’ that captures something of the trippy electronica of pioneering trumpeter Jon Hassell's work. On ‘What the Water Brings’, Rabbia thoughtfully integrates percussion and electronica, matching them up with close attention to sonic nuance while ‘Flotsam’ and ‘Wadi’, with Petrella's Arve Henriksen-like ethereal flutters, are fleeting moments of post-industrial chill. They bring to a close a seductively atmospheric recording that nevertheless risks being merely scenic backdrop.
