The Smashing Pumpkins performed at Lollapalooza on Wednesday, featuring a reunion with Melissa Auf der Maur and a surprise appearance by Barry Williams [1].

The performance serves as a high-profile warm-up for the band's upcoming 30th anniversary tour for the album "Mellon Collie and the Infinite Sadness" [1, 2].

During the set, the band brought out Barry Williams, known for his role as Greg Brady on "The Brady Bunch," to perform "It's a Sunshine Day" [2, 3]. The unexpected collaboration added a nostalgic element to the Chicago-based group's return to the festival stage [3].

The setlist included performances of "War Dreams of Itself" and "Dorian" [1]. Melissa Auf der Maur also joined the band, marking a reunion for the musicians on the Lollapalooza stage [1].

This appearance marks a significant milestone for the group, as they had not played at Lollapalooza since 1994 [4, 5]. The return to their hometown festival aligns with the preparations for their September tour dates [1, 2].

Olivia Rodrigo also made a surprise appearance during the event, adding to the eclectic nature of the pre-show festivities [4].

The Smashing Pumpkins, native to Chicago, haven't played at Lollapalooza since 1994.

The return of The Smashing Pumpkins to Lollapalooza after more than three decades signals a strategic effort to leverage nostalgia ahead of their 30th anniversary tour. By blending 1990s alternative rock with unexpected pop-culture cameos, the band is positioning the upcoming tour as a celebratory retrospective rather than a standard concert series.
