Smashing Pumpkins frontman Billy Corgan surprised fans by joining YUNGBLUD on stage for a powerful performance of their collaborative track “Zombie” during the British rocker’s special Lollapalooza aftershow party in Chicago on Thursday night (July 30).

With The Smashing Pumpkins scheduled to headline Lollapalooza the following day, Corgan still made time to support his friend Dominic Harrison (YUNGBLUD). The pair closed the aftershow with their reimagined version of the Grammy-nominated hit, delivering an emotional and intense live take that left the crowd buzzing.

Fan footage captured the moment, showing the two artists performing with clear intent and mutual respect. Observers noted how meaningful the collaboration appeared to YUNGBLUD, while Corgan looked equally proud to share the stage. The performance highlighted the chemistry that first sparked when the pair connected at Black Sabbath’s “Back To The Beginning” show last year, eventually leading to the studio version of “Zombie” released in early 2026.

That studio reworking, which features Corgan’s distinctive guitar work and vocals alongside the full Smashing Pumpkins, gave the original track a heavier, more urgent edge. YUNGBLUD has previously credited Corgan as a major influence during the making of his album Idols, describing the collaboration as a dream come true.

The live reunion at the Lollapalooza afterparty (reported at The Riviera Theatre) offered fans a rare chance to see the partnership in person, bridging generations of alternative rock. As The Smashing Pumpkins prepared to take the main stage at Grant Park the next day alongside Charli XCX, Corgan’s guest appearance served as a memorable pre-show highlight for the rock community.

The moment underscored the ongoing creative bond between the two artists and gave “Zombie” fans a thrilling live chapter in the song’s story.
