My latest reviews for All About Jazz should be of interest to ECM fans. The first is of a concert at New York’s Birdland given by Sheila Jordan, who reunited with pianist Steve Kuhn for a week of stellar performances. The second is of a concert given at Cornell University by the Ravi Coltrane Quartet. Among the band was pianist David Virelles, who stole the show with a tune from his ECM leader debut, Mbókò.
