Good question. The jury is out! It is hard to know in terms of cold hard fact. What we do know is to go on some reliable rankings if not fully disclosed metrics. Some things that are shifting a few units and that aren't reissues in the UK official jazz and blues album top 30 chart's top 10 (applicable from 12-18 February) are Various Artists' Blue Note Re:imagined, a platter that a Universal top suit Tom Lewis was pretty keen on getting behind in the trade press at the time of release. It resonates with younger jazz fans a good deal although for some of the more grizzled, marlbank included, hearing classic Blue Note from back in the day is still good all, any, day. Has ''the 'guard''' really changed? A difficult if inconvenient question especially if inclined to vainglory for the present but one that needs to be addressed given how extraordinary Wayne Shorter and Herbie Hancock were to name but 2 greats for instance back in their Blue Note pomp. Nubya Garcia's Source; and Fergus McCreadie's Cairn are also in the top 10. Fergus' record, as noted recently, is the best Scottish jazz record since Tommy Smith's solo on Mira stole the show communing with Arild Andersen and co and there is more quantity. Most of the rest of the top 10 are reissues or old records that are still selling and that is usually the case with the Official UK Jazz and Blues chart. Plus ça change. It all in a certain sense registers but hardly holds up a mirror to the scene. Link: to the chart
