AC/DC has postponed the rest of its U.S. tour because doctors advised singer Brian Johnson "to stop touring immediately or risk total hearing loss."
The band said in a statement that the 10 postponed dates, which run from March 8 in Atlanta to April 4 in New York, would be made up later in the year, "likely with a guest vocalist."
Fans can either save their tickets for one of the future shows or turn them in for a refund.
The Rock and Roll Hall of Fame band also had tour dates scheduled in Europe starting on May 7, but those concerts have not yet been postponed.
The news is the latest of many setbacks for the band.
That same year, longtime drummer Phil Rudd was arrested and accused in a murder plot. He later pleaded guilty to making threats and drug charges, and is no longer part of the band.
AC/DC was formed in Australia in 1973 by Scotland-born brothers Malcolm and Angus Young. Vocalist Bon Scott joined the following year along with drummer Rudd and bass player Mark Evans, forming the lineup that would record many of the group's earliest hits.
Evans was replaced by bassist Cliff Williams in 1977, and Johnson joined in 1980 after the death of Scott. Johnson's first album with the band, "Back in Black," remains the group's best-selling record and one of the top-selling albums of all time.
The band also has a reputation as one of the loudest in the world. Guitar company Gibson said AC/DC's "Back in Black" tour reached 130 decibels, leading to complaints from promoters. According to Purdue, that's the volume of a military jet with an afterburner taking off of an aircraft carrier from just 50 feet away, and beyond the 120-decibel pain threshold.
While the band's concerts are no longer quite that loud, they remain known for volume, even using cannons on stage for the song "For Those About to Rock (We Salute You)."
If Johnson doesn't perform again, his final show with the band will have been on Feb. 28 in Kansas City, part of which can be seen in the clip above.
