AC/DC have been forced to postpone the U.S. leg of their Rock or Bust tour over health concerns for lead singer Brian Johnson.
A statement released by the band on Tuesday states that Johnson, 68, has been “advised by doctors to stop touring immediately or risk total hearing loss.”
The band’s U.S. shows from March 8 in Atlanta through April 4 in New York City will now be rescheduled for later in the year, “likely with a guest vocalist,” according to the release.
“More information regarding these rescheduled shows to come,” the band’s announcement says. “Current ticket holders can hold on to their tickets for the rescheduled dates or receive a refund at point of purchase.”
The Rock or Bust tour began in April 2015, and took the group to countries like Germany, Scotland and Denmark.
Johnson’s hearing problem is the latest difficulty to hit the rock band. In September 2014, Malcolm Young, the group’s rhythm guitarist and founding member, was forced to retire because of dementia.
