I hope you all don't mind, but here is a short break from the regular discussion.
Any musician knows you have to rehearse if you're serious about the gig(s) coming up. You need to know the tunes, tempo, time signature, changes in structure, etc. It's also good to know what time to be at the gig. Basically, if you're playing with more than one person, it's good to agree on some things before you begin.
I've been to rehearsals, (jazz gigs) that lasted two or three hours. I've been to some where the rehearsal took place while doing a sound check. I've been to more than one where the rehearsal was conversation between the players. I guess it just depends on the situation.
It sucks to be late. It sucks more if it's you. It especially sucks if you are the only one that shows up. Late means you're playing catch up and somebody has to walk you through what's going to happen.
Late means you really don't give a sh*t, or somebody died.
The Lounge Lizards recorded a song entitled, "Where Were You.?" A fun and serious musical commentary about the business of the gigging musician.
I've listened to this many times and never fail to laugh out loud.
I hope you have as much fun listening to this as I do.
Happy Tuesday!
