Hardwell is set to return to Tomorrowland this July with a special performance marking the 10th anniversary of United We Are, his debut solo album. He will close The Great Library stage during Weekend 1, which takes place from July 25 to 27 in Boom, Belgium.

The Dutch artist announced the concept on social media with a message to his followers:

"4 more weeks until I close The Great Library at Tomorrowland 2025 and I want to celebrate the 10-year anniversary of United We Are, my debut solo album from 2015, together with you there. Which tracks do you want to hear the most during this special UWA anniversary set?!"

United We Are was released in 2015 and included collaborations with Tiësto, Jason Derulo, Fatman Scoop, W&W, Bright Lights, and Amba Shepherd. The release featured both vocal-led singles and festival material that shaped Hardwell’s early identity as a solo act. Titles like “Follow Me,” “Echo,” “Young Again,” and the album’s namesake were heard regularly across large-scale stages during that period and are still associated with his earlier sound.

Since the announcement, many fans have responded with their personal picks. Some are asking for “Sally,” while others are hoping for more emotional selections such as “Where Is Here Now” or “Colors.” While the full setlist has not been confirmed, the direction of the show suggests it will focus entirely on music from this album.

The Great Library stage is known for its theatrical presentation and narrative design, making it a fitting environment for this kind of album-focused tribute. The upcoming performance gives Hardwell a chance to revisit an earlier phase of his journey and reconnect with longtime supporters who followed him during that era.

His anniversary set brings a unique moment to Tomorrowland 2025’s first weekend. More than just a headline slot, it’s a rare opportunity to hear one of his most talked-about albums brought back in full form, live on one of the festival’s most creative stages.
