Some of music's hottest artists, including Nine Inch Nails mastermind Trent Reznor, Pearl Jam, Weezer, R.E.M., Neon Indian, Edward Sharpe & the Magnetic Zeros, and Circa Survive are supporting a new film called Countdown to Zero to make their collective message clear: No more nukes!

Weezer singer-guitarist Rivers Cuomo isn't shy about his obsession with heavy metal -- just look at dude's high school senior class photo, which graced the cover of his latest solo album.

As the U.S. Men's Team celebrates their victory over Algeria and advances to the next round of the 2010 World Cup in South Africa, Los Angeles power-pop outfit Weezer has released a new video for "Represent," their fight anthem to help the hometeam keep winning. Watch the video below.

Nowadays, Weezer's Rivers Cuomo squanders the majority of his genius on KISS-lite arena riffs and regressive rhymes about malls and homies (see: 2009's Raditude and the preceding two albums), but his musical prowess isn't dead; it's just dormant.

While the stages raged Saturday at the Bonnaroo Music & Arts Festival in Tennessee, fans were treated to intimate interviews at Harley-Davidson's tent, where some of the weekend's biggest stars stopped by to chat with SPIN.com's Peter Gaston, answer audience questions, and ride motorcycle simulators.

If you'll be in Manchester, TN, this weekend to rock out at Bonnaroo, be sure to stop by the Harley-Davidson tent (in Centeroo, near the Other Tent and the Ferris Wheel) for exclusive SPIN interviews with some of this year's performers!
