JOHN FOREMAN: I had a great time working with Mark Belcastro and everybody at the Cavern Sound Studios, both on the Red Ball with Hugh Jackman, and the Edelsten Wedding. Both of these major events were very professionally put together. The orchestra assembled by Mark was fantastic, Damien Montalto”s charts were great, and the production standards were very high. I would be glad to work with this team again.

 XEN- Trumpet Events: “ I really don't know how to express my level of gratitude to your part in the Wedding of the Year for Geoffrey Edelsten and Brynne Gordon You are an incredible talent,........your work ethic and attention to detail under extreme circumstances is unbelievable, if I had realized how huge the end product would be when we first started out, I would have had serious doubts about attempting it, you took each idea and made it into something spectacular without ever mentioning the almost insurmountable work load it took to achieve each section, you gave me the opportunity to keep going bigger and better......even when we were all a bit overwhelmed with the scale of what we were trying to achieve, you never tired.......you just kept going, never once compromising the quality.

And YES you were right about everything; even the play on’s.......and you may quote me!

It's an honour to work with you...only onwards and upwards from here”!!!!

 TOM BURLINSON: "I have worked with Mark Belcastro from the Cavern Sound Studios as a musical contractor on a number of occasions, including a performance with a 16 piece big band at the annual charity event The Red Ball in the Palladium Room at Crown Casino. Mark has always provided musicians of the highest calibre, assisted with musical arrangements when necessary, and behaved with courtesy and professionalism. I would happily recommend his services"
