In June 2003, shortly after releasing debut album Mary Star of the Sea—Billy Corgan's first major post-Smashing Pumpkins venture featuring David Pajo from Slint and Matt Sweeney—Zwan performed at Pinkpop, Europe’s oldest annual festival in Landgraaf, sharing the bill with Evanescence and Deftones. The hour-long set, captured in professional quality, traced Corgan's shift from grunge chaos to melodic indie-rock with folk infusions, where guitar passages in "Jesus, I" and "Mary Star of the Sea" built to a climax. This performance, brimming with the supergroup's spontaneous chemistry, highlighted Zwan's ambition to revive 90s spirit in a festival setting.
