Do you like Metallica? The heavy metal bank that came from Los Angeles, Ca.?
Yeah that's one of my favorite bands. I love their album called Ride the Lightning.
Lars Ulrich, formed them in 1981 along with James Hetflield. 
Right, they had Dave Mustaine at one point too, but then he left/got kicked out.
I think the current members are Hetfield, Ulrich, Kirk Hammett and Robert Trujillo.
It sounds right, they used to have a different bass player before Trujillo, but I can't remember his name right now.
It is sometimes called thrash metal  . Death Magnetic was popular too.
Metallica I believe is considered one of the four gods of thrash metal, not sure who the other 3 are though.
