Well it wasn't really a masterclass so much as 'an evening with', but in fairness it was very interesting still and very enjoyable.
Seeing some of the guys through the three differing periods who do this was interstng plus to hear about what they did and why they did it, and why it's different now.
As someone breaking into music photography is would have been useful to get some tips on how to get passes for events and how to approach publications who you want to send you along. Thats the difficult bit really.
Anyway, WELL worth the effort and definitely worth the entrance fee.
