After kicking off their US stadium tour with the first of two hometown Seattle shows that featured guest Brandi Carlile and a cover of The White Stripes, among others, earlier this week, Pearl Jam returned to Seattle’s Safeco Field on Friday for round two, which held its own surprises like sit ins from Soundgarden guitarist Kim Thayill and more, plus tribute to that band’s late frontman and longtime friend of Pearl Jam’s members and the Seattle grunge scene at large, Chris Cornell.

As Rolling Stone reports, near the midpoint of the set, Eddie Vedder and company offered their debut of Cornell’s “Missing,” honoring the dynamic singer who passed away last year. The cover kicked off a night that would nod to Seattle’s grunge heritage, just one day before the city’s Sub Pop Records celebrates its 30th birthday with an all-day festival (and a mayor-approved “Sub Pop Day” in Seattle). The label gained notoriety in the late-‘80s and ’90s for aligning itself with grunge icons like Nirvana and Soundgarden.

The local tributes continued during Pearl Jam’s first of two sets, when the band covered “Crown of Thorns” by Mother Love Bone, a fellow Seattle group that predated Pearl Jam and featured the band’s members Jeff Ament and Stone Gossard. For the next song, the group brought out Soundgarden guitarist Kim Thayil for a cover of MC5’s “Kick Out the Jams,” with Thayil wearing a shirt with Cornell’s image on it (Pearl Jam drummer Matt Cameron, who also drummed for Soundgarden, wore one of that band’s shirts as well).

After an eight-song first encore, Pearl Jam returned for another eight-song offering to end the night, and the second encore featured the return of Thayill, along with two members of another Seattle/Sub Pop grunge outfit, Mudhoney: Steve Turner and Mark Arm. The three guest musicians joined the host band for covers of Iggy Pop and The Stooges’ “Search and Destroy” and Dead Boys’ “Sonic Reducer.”
