Ours is a Barenaked Planet, or so the quirky rock band Barenaked Ladies would have us believe. In the years since breaking with their music label and going indie, they've overhauled their practices "from stage to studio" to make their music more planet-friendly. At each stop on their recent U.S. tour, they erected an "eco-village," bought carbon offsets, fueled their fleet of buses with biofuel, and distributed their albums on USB flash drives -- portable hard drives the size of your thumb -- instead of waste-heavy CDs. The vision is the product of a collaboration with Reverb, a nonprofit that works with other green-minded artists such as Bonnie Raitt and Alanis Morissette "We're just activists in rock-star clothing," says Morissette. Rock on.
