If "Cuban piano player" suggests human loops-operators playing endless chord vamps under seductive vocals, Ramon Valle is a Cuban piano player coming from a different place. Like a 21st-century Reuben Gonzalez, Valle is a relaxed virtuoso with a light, intuitive touch but a flood of sound at his disposal, and a raft of influences driven, but not overwhelmed, by Cuban dance traditions.

Valle was in London with a trio to launch a showcase week for Germany's ACT label, a pop-oriented offshoot of Warners that jumped ship in the early 90s to record new world-jazz and fusion, most successfully Esbjorn Svensson's take on it. Valle upholds the label's reputation for spontaneous but accessible new-jazzy sophistication, and his show presented a wilful acoustic improviser working in a trio of equals.

As on his new album, No Escape, Valle balanced a lissome lyricism with an openness to letting the ensemble sound float. Bassist Omar Rodriguez Calvo was featured for his vivacious solos, often against drum rejoinders from Liber Torriente that suggested wider percussion than he had. Valle let them converse for extended periods before intervening with a throwaway line - a hinted, ambiguous chord, a Bill Evans-like piano figure slipping away into a murmur.

On unaccompanied sections, Valle was at his most unpredictably loquacious. He would erupt into whirling keyboard runs and fluttering trills, before finally bringing in a pumping Cuban-dance riff - but even when it arrived, Valle's variations over it had a wild looseness. A pause, then a sonorous chordal intro brought on a gentle samba and another bass reverie for Rodriguez Calvo, followed by a dark, Spanish-sounding theme. Clear melody hooks were rare, and Valle's work was sometimes preoccupied and distant. But his was a skilful trio of improvisers, avoiding the obvious tracks.
