The Metal Box is a weekly web series posted each Friday where we discuss all things hard rock and heavy metal: news, videos, interviews, live concerts and more.

This week we talk about Ozzy Osbourne's announcement of a 2018 Farewell Tour. Watch video above.

Ozzy rose to fame as lead singer of Black Sabbath in the 1970’s, a band regarded by many as the world’s first heavy metal band. After being fired by the band in 1979, he launched a successful solo career in which he released many multi-platinum albums. He has sold over 100 million records worldwide. Ozzy is known to many as “The Godfather of Heavy Metal” and he was inducted into the Rock and Roll Hall of Fame with Black Sabbath in 2006.

Black Sabbath announced in September of 2015 that the band would be embarking on their final tour called 'The End' in 2016. The tour included two nights at Madison Square Garden New York City in Feb. and some summer dates.
