I saw it mentioned in UK Jazz magazines - there was talk of the tempting prospect of seeing Marcus Jam "after hours" with Herbie Hancock and Roy Hargrove !!
There are lots of these Jazz festivals in Europe in the summer and I suppose it's a good steady income for the 'name' players, plus it gives some newcomers a chance to get on the bill and it represents a pretty good deal for the European Jazz fans - a chance to see all the US acts we miss the rest of the year!
