Jaco Pastorius

Known for his work with Weather Report, Joni Mitchell and Pat Metheny, Jaco Pastorius was one of the most inventive bass players in music history. He is the only electric bassist in DownBeat magazine's Jazz Hall of Fame.

It seems an unlikely match.

In one corner, you have Metallica's Robert Trujillo. The most popular heavy metal bassist alive, he prowls beast-like across arena stages, rumbling guts with the low B on the 5-string instrument he slings to one side like a battle ax.
