Hi there This is an interesting one and I know you will have an answer or I hope you do. I have looked up Boban Markovic on the web (he is on at the BRASS festival in Durham) and found a film clip of him winning the 'Golden Trumpet' but what kind of 'trumpet' is he playing? I have not seen anything like it here! Looks and sounds great but please can someone tell me more? Who makes it and has anyone played one and what do you think? Can you buy one here and if so is it worth a shot! I am going to see him in Durham www.brassfestival.co.uk but I am interested in this now so I can practice to play at the festival if you think it is worth getting one. Brassy Boy!
