Everyone's entitled to their opinions of course, and yes I'm 43 and the late 70's early 80's were my apprenticeship, but all I'd say is, have some respect for someone like Jean, who is a very talented and influential bass player, regardless of if you know about him or not.
It matters not if it's Charlie Mingus, John Paul Jones, Mark King or Robert Trujillo you're into, they're all top class musicians who deserve some respect.
Jean and others like Tina Weymouth and Colin Moulding were my inspiration to start playing in the early 80's, and I love them all dearly for that.
