Aerosmith's Peace Out farewell tour is no more.

The band announced in a social media post Friday that its members made the "difficult, but necessary" decision to retire from touring due to 76-year-old frontman Steven Tyler's vocal cord injury, which postponed the tour in fall 2023.

"As you know, Steven’s voice is an instrument like no other. He has spent months tirelessly working on getting his voice to where it was before his injury. We’ve seen him struggling despite having the best medical team by his side," the band's statement read. "Sadly, it is clear that a full recovery from his vocal injury is not possible."

The statement continued: "A final thank you to you - the best fans on planet Earth. Play our music loud, now and always. Dream On. You’ve made our dreams come true."

At the The Peace Out tour launch in September 2023 in Philadelphia, USA TODAY music critic Melissa Ruggieri said the Hall of Fame rockers were in top form, saying "Tyler’s holy howl remains remarkably flexible, which he verified on the gravelly choruses of “Cryin’” and the prescient “Livin’ on the Edge,” and the band’s musicianship is in peak form for this victory lap."

After only a few shows, Aerosmith pressed pause on the tour and shifted dates to 2024 after Tyler fractured his larynx during a New York gig. They'd planned on a rescheduled 40-date run starting Sept. 20 in Pittsburgh, with the tour concluding Feb. 26, 2025, in Buffalo, New York.

"It was 1970 when a spark of inspiration became Aerosmith. Thanks to you, our Blue Army, that spark caught flame and has been burning for over five decades. Some of you have been with us since the beginning and all of you are the reason we made rock ‘n’ roll history. 

"It has been the honor of our lives to have our music become part of yours.  In every club, on every massive tour and at moments grand and private you have given us a place in the soundtrack of your lives. 

"We’ve always wanted to blow your mind when performing.  As you know, Steven’s voice is an instrument like no other.  He has spent months tirelessly working on getting his voice to where it was before his injury.  We’ve seen him struggling despite having the best medical team by his side. Sadly, it is clear, that a full recovery from his vocal injury is not possible. We have made a heartbreaking and difficult, but necessary, decision - as a band of brothers - to retire from the touring stage.

"We are grateful beyond words for everyone who was pumped to get on the road with us one last time. Grateful to our expert crew, our incredible team and the thousands of talented people who’ve made our historic runs possible. A final thank you to you - the best fans on planet Earth.  Play our music loud, now and always.  Dream On. You’ve made our dreams come true.
