The brilliant Wilton Felder played on one big hit, the Jacksons IWYB and a stonking groove it is to, but he was primarily a highly sought after saxophonist. For my money there's a whole tranch of little known post Jamerson players from that period worthy of consideration including Scott Edwards, Philly souls Ronnie Baker and Henry Davis who played on Love Hangover.. etc. All top flight studio guys who very few people have even heard of.
