The disco sound is summed up with the thumping and hypnotic bass sound. Whether it was produced by an actual bass guitar or a synthesizer doesn’t matter. Bassists really have the disco era a lot to owe for the furthering of their craft.
Bass players. The epitome of cool. There they are at the side or back of the stage thumping away on the strings and providing the rich deep groove of a song. I’ve never seen a bass guitarist get in a flap on stage. How can they be so relaxed?
