The second night of Pearl Jam’s special 20th anniversary festival at the Alpine Valley Music Theater in Wisconsin was just as full of surprises as the first night, as Eddie Vedder and the boys turned in a sprawling set Sunday that aimed to please casual PJ listeners and the most picky old-school fans alike.

Pearl Jam kicked off the night with an engaging rendition of ‘Wash,’ an outtake from their 1991 debut album ‘Ten,’ and preceded to tear through a 33-song set that touched on most eras of the band’s career. Hits like ‘Alive,’ ‘Daughter,’ ‘The Fixer’ and ‘Spin the Black Circle’ found their way into the setlist, as did fan favorites like ‘Yellow Ledbetter,’ ‘Satan’s Bed’ and ‘Elderly Woman Behind the Counter in a Small Town.’

Guest visits included Strokes frontman Julian Casablanca on ‘Red Mosquito,’ Crowded House singer Neil Finn’s son Liam Finn on ‘Habit’ and Frames/Swell Season singer Glen Hansard on ‘Smile.’ The show also featured an encore appearance of Temple of the Dog, as Soundgarden’s Chris Cornell jumped onstage to perform four Temple songs (they also rocked Saturday night's show). Temple of the Dog – essentially PJ plus Cornell – was a grunge supergroup formed in homage of Andrew Wood, the late singer of Mother Love Bone, the band spawned Pearl Jam after Wood’s untimely death from a heroin overdose.

The guest appearances wound down during the second encore as Mark Arm and Steve Turner from grunge veterans Mudoney joined PJ for a version of ‘Sonic Reducer,’ a punk staple made famous by the Dead Boys that has turned up on many Pearl Jam set lists over the years.

Earlier in the day, a slew of openers warmed up the crowd for the main event with even more surprise appearances, including singer-songwriter-painter Joseph Arthur (with PJ's Matt Cameron, Jeff Ament and Mike McCready backing him), New York hipsters the Strokes (with Queens of the Stone Age's Johh Homme sitting in on 'New York City Cops,' and Neil Finn (with Vedder adding backing vocals).

Not a bad way to celebrate 20 years of Pearl Jam, and here's hoping for 20 more. As Vedder announced halfway through his band's set, "[It] doesn't make us feel old. It feels like a rebirth, a new beginning."
