The Surprising Age Gap: Twins vs. The Rhythm Section

The most striking detail about the Greta Van Fleet members' ages is the tight, three-year gap between the oldest and the youngest. The Kiszka twins, Josh and Jake, were born in 1996, making them 29 in 2025. Their younger brother, Sam, and drummer Danny Wagner, were both born in 1999, making them 26 and 25, respectively, as of late 2025.

How the Ages Define Their Career Trajectory

This small age difference is crucial to understanding the band's history and their almost instant success. When Greta Van Fleet officially formed in 2012, the twin brothers were only 16, Sam was 13, and Danny, who joined a year later, was 14. This means they were all still teenagers when they began writing the material that would launch them to global fame.

• Early Start: The band was performing in local Michigan bars and festivals while they were all still underage, building a raw, organic following long before their first major EP, Black Smoke Rising, dropped in 2017.
• Grammy Success in Their Twenties: By the time they won the Grammy Award for Best Rock Album in 2019 for From the Fires, the Kiszka twins were only 22, Sam was 19, and Danny was 19. Such a major industry accolade at that age is extremely rare, solidifying their status as rock prodigies.
• Musical Maturity: Despite their youth, their music often sounds decades older, leading to the infamous Led Zeppelin comparisons. The combination of their young ages and old-school sound creates a unique tension that has defined their career.

The twins (Josh and Jake) are at the very tail end of the Millennial generation, while Sam and Danny are firmly Gen Z. This generational blend, though small, subtly influences their approach to music, blending classic rock reverence with a modern, digital-native sensibility that connects with a diverse, multi-generational audience. The twins, as the elder statesmen, often handle the more conceptual and lyrical heavy lifting, while the younger members anchor the band with a sophisticated, yet grounded, rhythm section.

Greta Van Fleet’s Latest News and Future Plans (Late 2025)

For fans curious about the band’s next move, their current ages place them right at the peak of their creative and touring capacity. Following the massive success of their third studio album, Starcatcher (2023), and the subsequent world tour, the focus in late 2025 is shifting toward new material and a potential new chapter.

The Fourth Album Rumors

The band has been relatively quiet on the touring front in the latter half of 2025, which has fueled intense speculation about a new studio album. Their last release, Starcatcher, was highly praised for its conceptual depth and theatricality. Now, the buzz suggests that a fourth, currently untitled album is in the works, with a potential release window of late 2025 or early 2026. This new material is expected to build on the ambitious scope of their previous work while pushing their sonic boundaries even further.

The Starcatcher Tour Continues

While a full-scale new world tour is likely to accompany a new album, the band has continued to announce selective dates for their Starcatcher Tour into 2025, particularly in North America and Europe. This ongoing tour schedule ensures the band maintains high visibility and continues to connect their high-energy stage presence with their dedicated fanbase. The live shows remain a critical component of the Greta Van Fleet experience, showcasing the raw talent of the young musicians.

Side Projects and Personal Growth

The members are also exploring individual creative avenues, a sign of their evolving artistry. Jake Kiszka has garnered attention for his work on his side project, Mirador, which is expected to release music in the near future. These individual projects allow the members to flex different musical muscles and are likely to inform the sound of the next Greta Van Fleet record. Furthermore, the Kiszka brothers have been making appearances in other media, with two of them recently spotted in a Bruce Springsteen biopic, expanding their presence beyond the rock stage.

The Legacy of Youthful Rock Authority

The journey of Greta Van Fleet—from a small-town Michigan garage band to a Grammy-winning global phenomenon—is remarkable, and their young ages are central to that story. In a music landscape often dominated by pop and hip-hop, the Kiszka twins (29), Sam Kiszka (26), and Danny Wagner (25) carry the torch for a new generation of rock and roll. Their dedication to a classic sound, combined with their current, active career timeline, confirms that authentic, powerful rock music is not only alive but thriving in the hands of these surprisingly young talents.

As they enter their late twenties, the band is moving into a new phase of maturity. Fans are eagerly anticipating how this next chapter will manifest in their music, especially with the rumored fourth album on the horizon. The ongoing Starcatcher Tour dates in 2025 and the members' evolving side projects prove that the band’s creative engine is running hotter than ever, promising a future filled with more high-octane performances and classic rock anthems.
