Live music has always been about the unexpected, but lately, onstage collaborations have become some of the most talked-about moments in modern gigs.

When artists step outside their own setlists and invite someone else onstage, it can change the feel of a performance instantly. These moments often feel unplanned and unrepeatable.

Whether it’s a pop artist sharing the spotlight with a long-standing legend or a surprise guest appearing during a festival set, these collaborations regularly become the parts of a show people remember most.

Here are some standout onstage collaborations that highlight just how unpredictable live music can be.

Olivia Rodrigo x Robert Smith

This collaboration stood out for how unexpected it felt. Robert Smith joining Olivia Rodrigo brought together alternative history and modern pop songwriting in a way that felt natural rather than forced. Their performance highlighted shared emotional themes in their music and introduced each artist to new listeners. What began as a show-stopping Glastonbury moment has now taken on a life of its own. Rodrigo released the live EP Live From Glastonbury (A BBC Recording) on December 5, 2025, capturing the energy of the set for fans to revisit.

Olivia Rodrigo x Lily Allen at Glastonbury

Lily Allen appearing during Olivia Rodrigo’s Glastonbury set added a sharp and playful edge to the performance. Both artists are known for honest lyrics and strong personalities which made the pairing feel well matched. The crowd reaction showed how powerful a surprise guest can be when it feels authentic to the setting.

Elton John x Dua Lipa

This collaboration blended experience with modern pop confidence. Sharing the stage felt effortless as both artists brought their own strengths without overpowering each other. It also reflected how Elton John continues to support and collaborate with newer artists while staying fully relevant in live music spaces.

Gracie Abrams x Robyn

Performing Close To You and Dancing On My Own together created a contrast between quiet emotion and a well known pop anthem. Gracie Abrams brought a softer tone while Robyn delivered a familiar classic. The combination worked because both artists leaned into the feeling of the songs rather than trying to reinvent them.

Benson Boone x Brian May at Coachella

Brian May joining Benson Boone at Coachella was a clear meeting of generations. Seeing a legendary guitarist onstage with a rising artist gave the performance added weight. It also showed how classic rock influence continues to shape newer voices in live settings.

Sam Fender x Olivia Dean

Sam Fender and Olivia Dean's collaboration felt cohesive from the first note. Their shared approach to emotionally driven, soul-leaning songwriting gave the performance an easy, grounded feel, as if it had come together organically rather than being carefully planned. Sam Fender’s raw, stadium-ready delivery sat comfortably alongside Olivia Dean’s warm, controlled vocals, with neither trying to dominate the moment. It stood out because of its restraint and honesty, a reminder that the strongest live collaborations often come from genuine creative alignment rather than spectacle.

The Killers x Bruce Springsteen

Few collaborations feel as iconic as this one. Bruce Springsteen joining The Killers delivered a performance rooted in energy and shared musical heritage. It felt celebratory and powerful and reinforced how live music legends continue to shape modern stadium shows.

Blossoms x Mel C

Mel C joining Blossoms brought a sense of fun and nostalgia to the stage. The collaboration blended indie pop with a familiar voice from pop history and connected easily with the audience. It showed how unexpected pairings can still feel accessible and crowd focused
