Iron Maiden marked their 50-year legacy by launching a new festival, EddFest, held over 10–11 July at Knebworth, drawing around 50,000 fans across generations. The two-day event featured support acts including The Almighty, Airbourne, The Hu and The Darkness, culminating in a two-hour Maiden headline set, and highlighted how the band continues to attract both long-time devotees and a growing younger fanbase.

Alongside the live performances, the festival displayed decades of Iron Maiden memorabilia, from the 2006 tour's "tank commander" Eddie to Paul Di'Anno's stage jacket. Fans ranging from teenagers attending their first ever concert to those in their forties and fifties reflected on the band's 20 studio albums, two Grammy awards and recent Rock and Roll Hall of Fame induction, with a viral TikTok trend referencing the band also drawing in new, younger listeners.
