The bassist admits that he had to learn to "say yes" to other projects after Megadeth broke up in 2002 - but that juggling multiple bands and interests is an increasingly common practice in the music industry.

He says: "People called and said, 'Hey, you wanna write some songs? Hey, you wanna play a tour? Do you wanna play on a record?' And I had to learn to start saying yes to things.

"I'm in Megadeth - make no mistake, Megadeth is my band. But when I do go off and play some shows or cut a record or something with some other people, in today's world, and even in today's record business, that's much more understood, accepted and just kind of part of the culture we live in now.

"A lot of people are doing a lot more other things outside of just their band, and, to some degree, fans like it. They don't look at it as, 'Oh, there's problems at home. Why is he out playing on something else?'"
