Def Leppard guitarist Phil Collen has cleared the air regarding live vocal authenticity. He reassured fans that frontman Joe Elliott and the rest of the band perform completely live without relying on lip-syncing or backing tracks. This commitment stands despite their massive upgrade to a new high-tech visual production.
“Our new production is brand new,” Collen explained. “It’s this company called Luz, who are from Montreal, and they’ve done a lot of the stuff in the Sphere in Vegas. The Sphere raised the bar — you’ve gotta actually kind of keep up to it. If you see — like a couple of years ago, a Taylor Swift show or Beyoncé, it kind of really elevated.”
The guitarist stressed that maintaining this level of production requires constant evolution and dedication. “You have to keep doing that — you have to elevate if you wanna stay valid. So, we do. And this new thing is the most amazing set we’ve ever had. You constantly keep upgrading, updating, and getting better,” Collen said. “We really sing our vocals live. And, again, so many artists out there don’t do that. But to be able to pull that off, that means you’ve gotta rehearse and warm up and do all that stuff for hours and hours every day. It’s worth it, though. It’s real.”
Collen’s defense comes as Def Leppard continues to push the boundaries of live rock performance with their latest production setup. The band’s commitment to authentic vocal delivery reflects a broader philosophy about what it takes to remain relevant in modern live entertainment while maintaining the integrity of their performances.
Def Leppard’s third Las Vegas residency at Caesars Palace in February 2026 showcased the band’s most ambitious production to date. Elliott described it as “the best we’ve ever had by a country mile” and “visually insanely different to anything we’ve ever done.” The band completely scrapped production elements from their previous five to six tours. They created an entirely new stage show with a fresh setlist that pulled deep cuts from their catalog that hadn’t been performed in decades.
The residency featured songs like “White Lightning” from 1992’s Adrenalize, which the band hadn’t played since the ’90s. It also included newly released material such as the single “Rejoice,” which was specifically written to be part of the new Vegas show. Elliott noted that the band was “pulling out stuff we haven’t played in decades” and “stuff we’ve never played before.” This demonstrates their willingness to challenge themselves artistically while maintaining the live vocal standards that Collen defended.
The band’s commitment to reinvention extends to their recent recording output. Def Leppard released a cover of Ben E. King’s 1961 classic “Stand By Me” in January 2025. Earlier in June 2024, they unveiled “Just Like 73,” a single featuring a guest guitar solo from Rage Against the Machine’s Tom Morello. These releases underscore the band’s ongoing creative engagement and their determination to remain vital in the rock music landscape.
The band’s insistence on performing live vocals while simultaneously delivering world-class production represents a deliberate choice in an industry where many artists rely on backing tracks or pre-recorded elements. For Def Leppard, the hours of daily rehearsal and vocal preparation are not merely technical requirements but essential components of their artistic integrity. This ensures that every performance delivers the authentic rock experience their fans expect and deserve.
