Dutch jazz is in a healthy position at the moment, unlike Britain, where so many young players flirt half-heartedly with ancient folk or exotic world-music beats. Amsterdam's clubs boast several straight-ahead stormers, including guitarists Jesse Van Ruller and Martijn Van Iterson, plus Tineke Postma, a sensual young saxophone stylist who brings a feminine aspect to world-class improvisation.

Taking acoustic Miles Davis and Wayne Shorter as her muse last night, she wove complex yet emotionally accessible lines on alto and soprano saxophones with no visible effort apart from the occasional raising of her left shoulder. One could waste precious words describing how well she, bassist Frans Van Der Hoeven, pianist Marc Van Roon and drummer Martijn Vink performed numbers from her current album, A Journey That Matters, but her impact on a select audience that included two pillars of the House of Commons Jazz Appreciation Group, Mike Connarty and Bob Blizzard MP, said it all.

Tineke belongs among the top half-dozen female jazz saxophonists on anyone's global list. This London debut confirmed her to be in a technical and creative bracket well above our top distaff players, including Karen Sharpe, Ingrid Laubrock and Jo Fooks, but the club was only half full. I felt angry. Where were London's opinion-makers on a jazz week underwritten by Holland's state department? Luckily for them and everyone else, there's a second chance on Friday.
