Back in the day when the band was the draw and focus, not the production. If ya didn’t captivate the crowd the production wouldn’t. Basic light show that mostly just washed the stage with some color and some accent lights. Sound was not over processed and compressed, it reached out and grabbed ya. Keyboards were used a lot more, every band that had KBs they had a Hammond B-3 organ, which were made for churches, and they rocked it.
Some say, “you did all those bands”, but I was born about 5 yrs too late, these were the real bands of the 70s I really wanted to work. I missed that boat, unless they lasted into my time. Meh!
Today production is 70% of the show, you can thrown anyone up there.
I think concerts were more fun then.
