Enigmatic Cork guitarist Mark O'Leary is little known in Ireland, but he has a growing reputation abroad, thanks to collaborations with A-list players like Paul Bley, Jack DeJohnnette and Uri Caine.

This offering features VietnameseAmerican trumpeter Cuong Vu and the superb New York drummer Tom Rainey. Waiting is a tribute to Samuel Becket that ranges freely over the contemporary improvised landscape without ever really touching down anywhere solid.

There are moments of inspired coherence, but in general, this will only satisfy those who like their music free of all constraints.
