Armin van Buuren and KI/KI release debut collab ‘Put Your Bassline’ as official AMF 2025 anthem

AMF has unveiled its official 2025 anthem, ‘Put Your Bassline’, marking the debut collaboration between Armin van Buuren and KI/KI. The track arrives on October 24, just one day before their much-anticipated back-to-back set at AMF inside the Johan Cruijff ArenA, part of the 750 Years of Amsterdam celebration.

For the first time, two AMF headliners have co-produced the festival’s anthem, merging Armin van Buuren’s trance energy with KI/KI’s underground sound. The single perfectly captures the spirit of AMF’s II=I concept, which symbolizes unity through contrast. Moreover, this collaboration highlights the duo’s shared passion for intensity and progression while bridging their different sonic worlds.

“KI/KI and I come from different styles, but we share a passion for energy and progression,” said Armin van Buuren. “Put Your Bassline captures that balance of something driving and direct, but with both our identities in it.” KI/KI added, “We wanted to make something that represents both of us without compromise. It’s a straightforward club track built for the dancefloor and for this special AMF moment.”

Their joint set will take place on October 25 in front of 40,000 fans, joining a lineup featuring Hardwell, John Summit, Miss Monique, Oliver Heldens, Sara Landry, Sub Zero Project, and more. Released via Armada Music in collaboration with slash, ‘Put Your Bassline’ lands on all major streaming platforms on October 24.

Tickets for AMF are available at amf-festival.com, with Early and Regular phases sold out and Late Phase now open.
