You’d better prepare to face the elements—Earth, Wind & Fire, that is. One of everybody’s favorite funk/soul/R&B/disco/everything you can think of groups is returning after an eight year break with their new single “My Promise.” The single is taken from the group’s upcoming LP, Now, Then & Forever. The band is allowing their fans to get a sneak peak of the album with their release of a rehearsal performance video.

“‘My Promise,’ it’s a great song,” the band’s co-founder Verdine White told Rolling Stone. “Straight down the middle, Earth, Wind & Fire. No question about it.”

“We put in a sincere attempt to be and do Earth, Wind & Fire the way people have come to know and love it, to rediscover the essence of what that is,” added band member Philip Bailey.

Now, Then & Forever is due out on Sept. 10, and the band will embark on a North American tour starting with a show in the San Diego Civic Center on Sept. 6. You can check out the teaser rehearsal video for “My Promise” below.
