I remember when Fair Warning came out, a guitar player friend of mine who was into anybody who played with facility commented that Eddie Van Halen & Jan Hammer were starting to sound like the same player, just on different instruments.
That, I thought, was a very interesting way to hear things, so I tried listening to Van Halen (then, anyway, obviously things changed as the years passed) as a pop-fusion band instead of a straight-up rock band.
It didn't not work, I'll say that.
