There's overachieving, and then there's these guys. Do they not know when to stop, or do they have life figured out? Either way, these 10 artists know how to rock in multiple bands without losing their cool.
10. Jack White: This guy has band ADD, and can't seem to settle down. But hey, if it ain't broke. Between the Raconteurs, The White Stripes, Dead Weather and his solo career, Jack's nowhere near hitting the road.
9. Josh Freese: This drummer's resume is basically any rock fan's fantasy, and consists mainly of Devo, Weezer, The Vandals and A Perfect Circle. That's sweet, what you do, Phil Collins. Meet Josh.
8. Damon Albarn: Lead vocalist of Blur and vocalist, songrwriter and instrumentalist for the Gorillaz, Albarn has his hands full now that Blur's made a so-called "comeback."
7. Eric Clapton: Yes, he's had a lengthy solo career and is just the best, hands down. But remember Cream? He was also part of a pretty killer band called the Yardbirds, as well as Derek & the Dominos. Rock 'n roll isn't just a young man's multitasking game.
6. The Traveling Wilburys: Because super groups are standard for the rock star who doesn't have an off switch. The double dippers in this one are Bob Dylan, George Harrison, Roy Orbison, Tom Petty and Jeff Lynne. That's how you do it.
5. Paul McCartney: McCartney just couldn't "Let it Be" and had to dabble in not only The Beatles, but Wings as well. He's doing pretty OK for himself, I guess.
4. James Mercer: Anyone who went through an alt phase knows who The Shins are, who had Mercer as its lead guitarist and vocalist. He was also in the fun band Broken Bells, in which he made sweet, sweet music with Danger Mouse himself Brian Burton.
3. Ben Gibbard: The man behind Death Cab for Cutie is also half of the Postal Service. Because, why be an indie god in just one band?
2. Brittany Howard: Move over, fellas. Although fairly new to the music scene overall, Howard maintains the glorious Alabama Shakes, and just kicked off her first album with an equally fabulous band called Thunderbitch. What is it the kids say today? Don't "sleep" on this one.
1. Dave Grohl: Your not-so-savvy friend may have committed sacrilege and said something like, "Wow, that drummer looks just like Foo Fighters' lead singer" when watching a Nirvana music video. Cut them some slack. It's not often you find someone who can so seamlessly have two successful music careers independent of one another, as Grohl has.
