Konitz, who will turn 90 next October, continues to plough a lonely furrow. Despite his occasional stylistic influence on such as Wayne Shorter or Mark Turner, he follows the Tristano model of constantly reworking old standards and seeking to create fresh melodies on their chords, such as ‘Thingin’’, his original simplification-and-distortion of ‘All The Things You Are’. He delights in springing surprises, so that the opening ‘Stella By Starlight’ starts with 32 bars of unaccompanied Konitz, followed by equal amounts of unaccompanied solos by the other quartet members, before there's any ensemble playing. By now his alto sound, though immediately recognisable, seems appealingly frail in the manner of the later years of Lester Young – although the fact of devoting parts of two tracks to vocal rather than saxophone improvisations, with greater invention than intonation, may be a surprise too far for some fans. Barron and the two unrelated Washingtons do all that's expected, in the way of soloing and accompanying, and you can admire Konitz's desire to keep making it new, while realising that this doesn't stand close comparison to his best earlier work.
