Getting asked back is one of the highest compliments.
But getting asked back doesn’t happen by being really good bothering the promoter eight weeks after your last gig there.
It doesn’t happen by focusing on getting asked back.
It happens by putting on a show that isn’t concerned with next time but rather lighting the full stick of dynamite, pulling the pin and letting it fly, turning it up and tearing off the knob, shakin the lakes and rockin the docks. (I grew up in Minnesota, I heard someone say the lakes bit when I was a kid.)
Getting asked back means you were incredible last time.
This time is next time’s last time. Make it incredible.
