I will chime in with my $.02
I've done Rock, Country, Pop and Jazz Tours. One thing that I noticed is that there's a code of mutual respect among musicians and tour support personnel regardless of genre.
Case in point: I was playing with Joanna Dean, a Hard Rock singer signed to Polygram in the Hair Metal era of the late 80s when I ran into Jazz Guitarist Joe Pass in Copenhagen. Joe was playing at Tivoli Gardens with Charlie Mariano. I half apologetically explained to Joe that I loved his work but I was over here with a Metal Band and he stopped me right there, "Don't apologize! You've got a gig! Good for you!"
More often than not a good bassist or guitarist at that level can play many, many styles well. I've never run into a touring Pro Rocker who dogged another Touring Pro Musician, regardless of style. When I was out with John (Dukes of Hazzard) Schneider we ended up staying at the same hotel as Bon Jovi and they gave us VIP passes to their show that night and pretty much the Royal Treatment (this was in 1987, the Slippery When Wet era).
When I was out with Engelbert Humperdinck we stayed and played at The Foxwoods Casino when the Yellowjackets were playing at the B B Kings club there. I ended up hanging out with Jimmy Haslip, Russ Ferrante and Bobby Mintzer and they were totally nice and didn't dog me for my gig. Jimmy, of course, was touring with the Great Rock Guitarist Tommy Bolin when he died.
I think it's a bit like Fans of NFL Teams. I live in Nashville and we hate the Baltimore Ravens. I know the players talk some smack but when the late Steve McNair was traded to them, I'm sure they welcomed him into their organization and he still kept all of his Titans buddies. A lot of this smashing other genres and trash-talking is more the province of "Fans" of bass and music styles rather than Pro Players. Nothing wrong with that-it's called Talkbass and there's no entrance exam to post. You just have to love bass.
I absolutely love Jaco and Jeff Berlin. I also absolutely love Billy Sheehan, Lemmy and the late Wally Voss (Yngwie's bassist and an absolute unsung Bass Hero) was a dear, dear friend. I try to listen to Music and not Categories.
I've got a recording session tomorrow in Chicago. It's Fusion. Chris Poland (Megadeath and O.H.M.) is overdubbing the guitar solos in LA. I don't care what style he calls himself-I just call him a Bad**s Guitarist and I'm honored we're on the same track!
