Aerosmith goes on hiatus as its frontman undergoes an operation

Aerosmith frontman Steven Tyler will undergo surgery this week for an undisclosed medical condition, forcing the band to cancel the rest of its North American tour, says the group’s publicist.

“Despite Aerosmith’s desire to keep the tour going as long as possible, Tyler’s doctors advised him not to continue performing to give his voice time to recover,” rep Marcee Rondan said in a statement, the Associated Press reports.

Rondan would not elaborate on the specifics of Tyler s condition, but said he is “doing fine.” Published reports have said the singer, who turns 58 on Sunday, has vocal problems.

Tyler is unable to perform for an extended period of time, Rondan said, adding that the band is on hiatus.

Aerosmith canceled recent concerts in Manchester, N.H., Pensacola, Fla., and Lexington, Ky., because of illness, though the tour press director did not disclose who was sick or the nature of the illness, the Associated Press reports.
