ARTISTdirect.com editor Rick Florino recently spoke to METALLICA bassist Robert Trujillo and constructed a playlist of what Robert's spinning.

"My four-year-old boy loves TOOL!" Trujillo told ARTISTdirect.com. "When I take him to school, we're playing TOOL all the time, so I definitely connect with them. There's a lot of bass in that group which is nice. They're a great band for a bass player to listen to. So believe it or not, my son and I are going through a big TOOL phase!"

He added, "I go through these real technical phases, and I listen to bands like MESHUGGAH and MNEMIC. It's stuff that's a little bit complex and takes a lot of patience. Lately, I've been jamming a lot to our music. I play through the new songs so I can keep fresh and keep them in my head. I can act crazier on stage if I can play them with proficiency."
