INTERVIEWSListen: New Pearl Jam Song Leaks

It's been a killer week for Pearl Jam fans. The alt-rockers opened their North American tour in Toronto with a bang, charmed Chicago with a pair of brilliant shows, and unleashed the high voltage music video for the first single single, "Fixer." And now the Seattle band's new song "Supersonic" has leaked!

Guitarist Stone Gossard penned the hard-rocking "Supersonic," off their September 20 release Backspacer, and it showcases Eddie Vedder howling at his melodic best. Listen below, and check back to SPIN.com for more from Pearl Jam's U.S. tour, which hits San Francisco's Outside Lands Fest this weekend.
