I also thought that disco would kill bass playing. It seemed that there were keys playing the parts I used to have, notes too low for me to go to, and if there was a bass player, s/he needed to back up on keys.
But I cannot let this thread slide through without propping up Cordell Boogie Mosson of Parliament and Funkadelic. If you have access to any of the old (70s) videos, check out Mosson. He (to many of us) defined funk, and it was usually in the spaces and air. It was the space between the notes, it was the hesitation while still being on the beat, it was going low when everyone else was going high. He was busy, but there wasn't clutter...does that make any sense?
(And in the videos I have, he has a Ric if that means anything...)
