I got back from the gig about two hours ago.
It went absolutely fantastic.
We played 6 songs, and someone else filled in for me on the last one.
I believe the setlist was thus:
I Love Being Here With You - Peggy Lee
Pollution - Tom Lehrer
Four - Miles Davis
Confirmation - Charlie Parker
Tenor Madness - Sonny Rollins
Corcovado (Quiet Nights of Quiet Stars) - Antonio Carlos Jobim
Since I've had so little time to learn jazz before tonight, I really dug in to the facial expressions and looking like I was having the time of my life, and afterwards there was much proof that that strategy was effective.
At one point I overpowered the singer a bit, and the band leader signaled for me to turn down. All I did was changed my dynamics, didn't touch the volume, and there was no further complaint.
What I was happiest to hear, though, was actually about the most embarrassing part of the gig that I think happens to everyone at least once or twice during their career: the provided cheapo cable pulled out of my
active bass.

(strangely enough, the resulting
POP was right on beat
)
However, I kept my cool, slowly turned around to turn down the gain and volume, plugged back in, turned the levels back up, and came right back in on verse 2.
The man in charge of the music department of a local college saw me, and told me he was really impressed with my playing and would love to have me there. Score!
It was a great night, and the band leader is now discussing taking me to Colorado next year, and into the recording studio before that! I am just so excited right now, I never thought that anything like this would happen to me.
I look forward to more reports like this. My next one will be next month.
Thanks for reading/listening,
