'Concert Photos' is the largest selection for now, containing live material taken in the last 10 years or so. ‘North Sea Jazz Photos’ are images from only the last few years of the festival. ’Concerts vintage' is earlier work and will be greatly expanded in the near feature, since a lot of material is still to be digitized. The same applies to the third catagory ‘Portraits’ and the last category ‘Backstage’.
