I recall many many years agoi when I played in a 60s covers band (yawn!) and we were playing Move It by Sir Cliff. The whole hall was up jiving away. The singer then signalled for me to stop playing so he could sing a verse sort of accapalla if you will and the whole crowd stopped moving. They all started again when I began the walking bassline again. People generally dance respond to what they feel, not what they hear. They dance to your BASSLINES to a large extent.
I thoroughly enjoy being the most powerful member of the band, I can control everything from my 4 strings.
As said above, just stop playing one day during a song and wait for the frustrated glances.......we are needed!!!
