Metallica's 2nd bassist, and one of the greatest metal bassists of all time. Along with Steve Harris of Iron Maiden, he was one of the first metal bass players to play complex bass lines. He also liked to play loud and often soloed (with distortion, and sometimes wah). Because of this, some people have reffered to him as a "lead bassist".
He co-wrote several great metallica songs, including Master of Puppets
and Orion (which was played at this funeral), and composed most of To Live is To Die, which was recorded as a tribute to Burton in metallicas ..And Justice for All
Cliff died September 27, 1986 after metallica's tour bus overturned in rural Swedan.
