Before MIDI? I didn't think there was even electricity before MIDI came around!
I have played in a venue where the electricity was supplied by a generator driven by a tractor as the mains power hadn’t reached the area yet. Well into the night down went the electricity and a voice called out “didn’t you fill the bloody thing up like I told yer”. A reply of “sorry dad”.
I can also recall our band sitting on tables with acoustic instruments during a blackout.
When I first started we used sing into Crystal mics plugged into a guitar amp. When we got a PA and diaphragm mics we thought we were made.
Yep times have changed.
