Rock duo The Black Keys, known for hits including “Lonely Boy” and “Gold on the Ceiling,” recently canceled a 31-stop North American leg of an international tour without giving a reason — but the band is assuring fans its members, Patrick Carney and Dan Auerbach, are “alive and well.”

The tour, called the “International Players Tour,” originally kicked off in Oklahoma on Sept. 17, and had dates through the fall in Atlanta, Austin, Dallas, Denver, Nashville, Philadelphia, Phoenix, Portland, the San Francisco bay area, Seattle, New York and Boston — among other places.

All of those dates are listed as canceled on Ticketmaster, and the band has not given a reason why.

The band tweeted to X, formerly known as Twitter, a promotional image for the tour with a “Please Stand By” label on top of it, along with the message: “The band wants to assure everyone that Dan & Patrick are alive and well.”

The tweet thread goes on to say that the band “decided to make some changes to the North American leg of the International Players tour” after playing in Europe.

“That will enable us to offer a similar exciting, intimate experience for both fans and the band, and will be announcing a revised set of dates shortly,” the tweet thread continues, stating that those who bought tickets would be fully refunded and would get the first opportunity to buy tickets when new plans are announced.

The Black Keys had released its new album, “Ohio Players,” in early April, including single “On The Game.”

The two musicians have known each other since the age of 8 or 9 growing up in Akron, Ohio, according to Vulture. They later moved to Nashville, and found major success with albums including “Brothers” and “El Camino,” the latter of which includes some of their most recognizable songs, like “Lonely Boy.”

Only one tour date still exists on the band’s website — a performance on July 6 at the NASCAR Chicago Street Race in Chicago.
