As many have said, the promo video needs to be more professional,
visually and audio wise.
A lot of bands go to great extremes and cost to get that right these days,
after all, it is still business at the end of the day, and you are in competition
I used to do plenty of cruise gigs, mostly the pit/orchestra/backing the productions shows,
and they were certainly better paid than the lounge or guest bands.
More than likely because you were on standard MU contracts, which meant weekly show fees,
show rehearsal fees if needed ( and usually were for cast), travel to and from port/airport and in port maning if you wanted it.
The lounge gigs where not so desirable because of long hours and some times day gigs or lunch time bar sessions.
Two or four week depping was also regular, the guys who were on long term contracts would
need the breaks. Those days are now gone, sadly.
I know a few younger single guys and girls who do cruise ships, and I was surprised at how low
the wages are these days. If you are single, still a good gig to do and you will save money.
Good for your chops, and of course, you get to see the world - great social life.
Good luck with it all.
