So what makes a new, free live set that PJ frontman Eddie Vedder played for 90 fans at a Microsoft event at their Seattle headquarters so special? Well, the setlist, mainly. The 20-song solo performance is filled with rare covers, everything from lead track "Trouble" (originally by Cat Stevens) to classics like John Lennon's "Imagine" and Neil Young's "The Needle and the Damage Done."
