I have two pairs of drums that can make a set of 4. Adams 23″ & 26″ and another pair I believe are Ajax 25″ & 28″. They have a romantic/modern sound, decay and maximum volume due to having thin Kalfo heads, L-shaped counterhoops, large collars and deep bowls. And so they are suitable for ensembles of 50 players or more.
With many thanks to the photographers and film makers who have allowed me to use their work; Stephen Tasker, Chris Christodolou (RCM), Tommy Pearson, Monika Rittershaus (Berliner Philharmoniker), Will Schofield, Glyn Matthews, Angus Bremner (SCO) and Zen Grisdale.
