Ahh yes, welcome to "the music biz".
Rarely does everything go as planned,
especially on a multi-band bill
(Five minute change overs? Rrrrright. lol).
My son plays, has subbed for me
and has learned to expect the unexpected through my experiences.
It's how you react/handle it that makes the difference between;
"What a bunch of dicks"
and
"Those guys were cool"
which can mean either call backs or black ball.
Wait till he gets to learn the meaning of "percentage of the percentage",
has to meet pre-sale ticket quotas (AKA: Pay-to-Play),
deal with corporate gigs that only pay out according to their invoice cycle
or the lying doorman who collects the cover charge, claiming only X amount of people when the club was full.
Then there's the "pro" headliners that limit your use of sound/light equipment,
eat up your sound check time (if you get any at all)
and forbid you to sell your merch for less than theirs.
The all too famous idiot who double books the night
and you show up to find another band already there
(which is the ultimate test of grace).
Do any of these scenarios sound familiar to anyone?
Call me jaded but nothing surprises me any more.
Just lead by example Dad-
Don't sweat the small shit and accentuate the positive.
