Rhino, the "new" Status Quo bassist since the eighties, once said in an interview (tired of comparisons to his predecessor Alan Lancaster who, inter alia, played mostly with downstrokes - even the fast stuff - with his pick while Rhino is a much more nimble finger player): "What people don't realize is that Alan - and I love his style - played to the best extent of his capabilites then". Rhino (not a nasty person) was indicating that while he was, within Quo, playing at a, say, 50% level of his capabilities, Alan - true - had done so at 95%. And you know what:
That is exactly why Lancaster's bass playing had a sense of urgency and perhaps unrelaxed forcefulness in it that Rhino's much more supple bass playing so totally lacks. Lancaster was fighting his limits and Status Quo sounded so much better for it. Lancaster himself put it down to his pick playing in an interview years later, but I believe he was missing the point or maybe didn't want to admit to how much better a bass player Rhino technically is. When Alan played a fast run, you could hear that he just barely made it, when Rhino does the same, it's effortless for him.
Another example: I saw "Hairsnake" in 1990, the Vai line up. I believe Vai is an utterly idiosyncratic player and a gifted musician and more fluid than even EvH, Satriani or Steve Morse. I love what he did with Alcatrazz on Disturbing the Peace. Everything he did at that Monsters of Rock gig was effortless, he made Vandenberg, Perry and Whitford (Aerosmith were seond on the bill) seem like klutzes on guitar. He was so sky-high above the other guitarist that he looked like he was taking the piss on them (I'm sure he wasn't even though he admittd today that he regrets in hindsight how much he overplayed with WS live making an hand injury ailing Vandenberg feel even worse). It was horrible. Like seeing an adult method actor take part in an amateur play of children. It grated so much it was physically painful to watch and hear.
Vai is effortless even in comparison to Malmsteen (certainly no technical slouch), just compare the two here (playing a Malmsteen composition):

That is not to knock Vai at all, in the right setting he can be lovely/breathtaking, but he too needs music that demands something off him. Vai would have been great with Miles Davis, I'm sure.
