“There’s an art to simplicity, and Jason Newsted brought that art. Cliff Burton was more aggressive, and a busier player”: The bassists of Metallica

Jason Newsted, Robert Trujillo,and Kirk Hammett of Metallica perform at Day Two of the bands' 30th Anniversary shows at The Fillmore on December 7, 2011 in San Francisco, California.

Bass Week: If you know your Metallica history, you'll know that Jason Newsted and Robert Trujillo aren't the only guys to have filled the bass chair with the thrash metal giants. The first, Ron McGovney, joined in January 1982, but his time with the band was to be short-lived.

The story goes that McGovney was at a concert in San Francisco with guitarist James Hetfield and drummer Lars Ulrich when they saw Cliff Burton play with his band Trauma.
