When I hear bass players talk about Jaco it's like two fat old bald guys standing on a corner as Paris Hilton walks by and one saying to the other "she's really not that hot" Here is the point, If Jaco had a dress on in the Shadow and Lights video, he still would have been a "Great Bass Player"
Okay now try and keep with me here... Jaco did more for the evolution of the electric bass then Jimmy Hendrix did for the evolution of the electric guitar.

And not only was he a great bass player, he was an over all great musician.
Look if you don't like Jaco that's cool with me.
If you can't make it through every track on a Wether Report recording that's cool too. I think it's really cool that you found a style of music that you like and Jaco just happened to be the bass player.
But I don't think it's cool when some one who couldn't play their way through a Blues Standard critiques the style, note choice or amount of notes played by any Jazz Musician.
Want to hear something that your small little 1 4 5 ears might like. Look for Ian Hunter's recording All American Alien Boy. Jaco plays on that one as well.
