Ozzy Osbourne will embark on a two-year “farewell world tour” starting in 2018.

On the trek, Ozzy — Rock And Roll Hall of Fame inductee and Grammy-winning singer and songwriter — will celebrate more than five decades as a performer (both as a solo artist and as lead singer of BLACK SABBATH, which formed in 1968).

This tour, expected to take Ozzy around the world with dates into 2020, will mark the end of global touring for the legendary artist, though he will continue to perform select live shows. Ozzy will be joined by longtime collaborators Zakk Wylde (guitar), Rob “Blasko” Nicholson (bass), Tommy Clufetos (drums), and Adam Wakeman (keyboards).

“People keep asking me when I’m retiring,” Ozzy says. “This will be my final world tour, but I can’t say I won’t do some shows here and there.”

Osbourne‘s farewell tour will kick off in May 2018 with shows in Mexico, Chile, Argentina and Brazil. Those will be followed by a couple of early June dates in Russia before Osbourne embarks on on a month-long European leg, including appearances at most of the summer festivals. The beloved rock icon will subsequently headline a North American concert tour produced by Live Nation, details of which will be revealed in 2018.
