I don't doubt the guy has talent in abundance (even though in the early days you'd have said he stole most of his chops from Mick Karn and Percy Jones),
Do we not all have to start somewhere? Why not learn from the best? If I was to go under the knife tomorrow I would want a surgeon who had learnt his chops at a top medical school not at the local pub.
I just find it a little hard to take on board that NIN now have a guy on board who (as a good friend of mine commented) has whored his way around the music business.
It must be truly awful earning a solid wage playing bass all the time. Being constantly asked to join this project or that project, do a bit of traveling and get to challenge yourself musically in innumerable different styles and situations must be a huge drag. Does your friend have a similarly high opinion of Lee Sklar, JMJ, Jaco, Marcus Miller, Nathan East, Bernard Purdie, Steve Gadd, Keith Carlock. Larry Carlton, Steve Lukather, Omar Hakim and all those classical soloists who just seem to wander aimlessly from one orchestra to the next ready to shred that Tchaikovsky concerto?
