In less than 24 hours, Greta Van Fleet's new single shot to No. 1 on iTunes.

The rockers from Frankenmuth, Michigan released "When the Curtain Falls" at midnight on Tuesday, July 17, 2018. Later in the day, the song jumped to the top of the iTunes rock charts and into the top 40 among all genres.

The foursome told MLive in a recent interview they plan to release their first album sometime this summer. "We're reshaping it and then get into mastering and hopefully release it soon. It's looking like late summer," said singer Josh Kiszka.

This isn't the first time Greta Van Fleet has seen a song go to the top of the charts. They released their debut studio EP in April 2017 and their double EP this past November. That double EP, "From the Fires," reached No. 1 on the Billboard U.S. Hard Rock Chart and their first single, "Highway Tune," reached No. 1 on Billboard's Rock Radio Chart for five consecutive weeks.

Even though they haven't even released their first album, the band is selling-out most of their shows in advance on their world tour which continues all summer. Here is our recent MLive interview with the band.
