GRAND RAPIDS, MI -- Have you wondered what life is like for a bunch of kids from Frankenmuth who all of sudden find themselves being called rock music's "next biggest thing"?

We will find out on Thursday (Sept. 14, 2017) when we sit down with 21-year-old twin brothers Josh and Jake Kiszka, their 18-year-old brother Sam Kiszka and their friend Danny Wagner, who is also 18.

Collectively they are Greta Van Fleet.

It's a band with an unconventional name, but it's their classic rock sounds that are turning the music world upside down.

The group's first single, "Highway Tune," is the No. 1 song in the country on Active Rock radio, and the band's dates are selling out coast to coast.

Tickets for Thursday's show at The Stache (inside The Intersection) sold out weeks ago.

Last week they opened up for Bob Seger, which they called an "absolute honor." The band has a string of European dates and major festivals, too, in the near future.

Has it all sunk in yet?

"Really, it's not. It just moves so quickly," Sam said in an interview before the Saginaw show with Bob Seger.

The band's four-song EP, "Black Smoke Rising," debuted Aug. 17 at No. 1 on the American and Canadian iTunes Rock Charts.
