Bush & Mammoth at Fillmore Denver

Some bands manage to age without losing the thing that made people care in the first place. Bush is one of those bands.

The British rock band returned to Denver’s Fillmore Auditorium in 2026 with a set that balanced their massive ’90s catalog alongside newer material, proving they are far more than a nostalgia act. Joining them was Mammoth (a band formed and fronted by Wolfgang Van Halen) making for a night that spanned generations of rock fans without ever feeling mismatched.

This was my second time photographing both bands, which always makes things a little more interesting. Knowing how performers move lets you anticipate moments instead of chasing them. Earlier this year I also had the chance to interview Gavin Rossdale, so it was fun seeing him back in his natural habitat: on stage, completely in command of a room.

Mammoth opened with the confidence of a band that has earned its place rather than relying on any famous last name. Wolfgang Van Halen continues to carve out his own identity with a modern hard rock sound built on memorable riffs, huge hooks, and musicianship that never feels like it’s trying too hard to impress. The band sounded tight from the first song, and “Wolfie” (as we’ve known him all his life) seemed genuinely happy to be playing for a packed Fillmore crowd that rewarded them with plenty of enthusiasm.

Then Bush took over.

From the moment the band hit the stage, Gavin Rossdale reminded everyone why he remains one of rock’s most magnetic frontmen. He never stopped moving, working every corner of the Fillmore stage while connecting with fans from the first song to the last. Even after all these years, he performs with an intensity that feels completely genuine.

That energy is matched by a band that continues to sound powerful live. The guitars hit with the weight fans expect from songs like “Machinehead” and “Everything Zen,” while new material from I Beat Lonliness fit seamlessly into the set. Of course, “Glycerine” brought one of the evening’s biggest singalongs, filling the Fillmore with thousands of voices.

Bush has always occupied an interesting place in rock history. While they emerged during the alternative explosion of the ’90s, they’ve continued evolving instead of simply replaying the past. Their newer songs don’t feel like obligatory additions between the hits. They belong there.

The Fillmore Auditorium once again proved to be an ideal venue for this kind of rock show. The room was packed with longtime fans who grew up on Bush alongside younger concertgoers discovering the band live, creating the kind of cross-generational crowd that only a handful of artists can still bring together.

More than three decades after breaking through, Bush continues to deliver exactly what fans hope for: loud guitars, memorable songs, and a live performance that never phones it in. They aren’t living off their legacy. They’re still building on it.
