Peacock is of course a known quantity, or certainly should be after 30 years on and off alongside Keith Jarrett, although that setting may not always display him to his best advantage. On the other hand Marilyn Crispell, who is of the same generation as Jarrett (i.e. a decade younger than Peacock), has given us decades of solid work, starting with people like Anthony Braxton and Roscoe Mitchell, but has often stayed beneath the radar of listeners not committed to free-jazz. If you’re of that ilk, you’ll perhaps be surprised to hear how melodic and unclichéd and, er, ‘free’ she sounds here. Apart from the two short unaccompanied tracks (one for each performer), most of the items have a clear ‘hook’ set up by piano or bass, and it’s only the three (out of 11 pieces) bearing a joint credit that build their momentum from non-thematic interplay. But the strength of the players is such that the interplay carries the listener along throughout.
