Greta Van Fleet is continuing to take the music scene by storm with their dynamic sound, which some would describe as Led Zeppelin-inspired.

The band, based out of Frankenmuth, performed at Sir Elton John's AIDS Foundation's 26th annual Academy Awards Viewing Party on Sunday, March 4, in West Hollywood, California.

John joined them onstage, playing keyboards.

"Whoever says rock music is dead is completely wrong," said John, who was quoted in the LA Times. "When I first saw them, they knocked me out.... They are going to be one of the biggest bands of the year."

The four-member band writes and performs their own music. It includes 21-year-old twin brothers Josh Kiszka on vocals and Jake Kiszka on guitars, younger brother Sam Kiszka, 18, on bass, and best friend Danny Wagner, 19, on drums.

John raised $5.9 million for his foundation, according to the report.

The quartet is currently in the studio working on its first album, which is expected to be released later this year.

"Each of us has his own set of influences, so that brings a great diversity to the music we make," said Jake. "Every one of our songs has its own unique complexities and we'd like for the full album to showcase that diversity, let people see what we can really do."

In February, the band announced dates for the first leg of its North American tour. The tour will kick off on April 13 at the Coachella Valley Music and Arts Festival.
