Jaco was the Jimi Hendrix of bass. Before him, NOBODY played at that level. Since his passing others may have eclipsed his playing but, make no mistake, he forged a new and expressive path that NOBODY had ever gone down.
Some of his work was sketchy, usually the result of his drug abuse and mental issues, but there was genius in the man. Hell, he was only 36 when he died. Consider how EVERY PLAYER in the 70s went running to the woodshed to try and figure out what he was playing. Nope, electric bass has never been the same since.
Much respect to Jamerson but there were others, Babbit, Kaye, Ralphie Armstrong, Stanley and others who might have been lotted with Jamerson, but NOBODY approached Jaco's genius other than, maybe, Jeff Berlin.
Ok, You know how I feel. ?
