I have this one as an audition piece in about a week,and listening to it,it sounds like 2 different bass parts.I found a live video of the song,and sure enough,there were 2 bass players. There are the root quarter notes,then there is the popping which is not real hot in the mix. I guess I need to find out some info from anybody that has played this one in a band setting. Did you stick to the root notes,or mix up the root and pop/slap techique? Thanks for the help!
