AC/DC will postpone the remainder of their U.S. tour as frontman Brian Johnson battles hearing issues. According to a press release, Johnson has been advised by doctors to stop touring immediately due to the rise of total hearing loss.

The band’s tour was set to roll through Atlanta on March 8, however that has been postponed along with the final 10 dates of the tour. A press release says the dates will be made up later in the year, likely with a guest vocalist.
