Lead singer Steven Tyler is expected to have surgery for an undisclosed throat condition this week.

The band stated that, despite its desire to keep the tour going as long as possible, Tyler’s doctors advised him not to continue performing and to give his voice time to recover.

Tyler will be on total vocal rest and can not perform for an extended period of time, so Aerosmith is on hiatus until further notice.

The band had been on the road since last October.
