Currently on their final tour, metal legends Black Sabbath were forced to cancel their January 30th show in Edmonton, Alberta due to frontman Ozzy Osbourne coming down with extreme sinusitis. The band's February 1st show in Calgary, Alberta has also been postponed. According to an update from Live Nation, details regarding rescheduled dates will be announced as soon as they are available.

Black Sabbath recently released the full video taking you behind the scenes of rehearsals for their final tour ever. Check it out below:

On the heels of their much-anticipated performances in North America, Australia, New Zealand and Europe, Black Sabbath will end the epic journey they began nearly five decades ago with another run of North American dates in fall 2016. These shows will follow a mix of summer headlining and festival performances throughout Europe.

The second run of North American dates kicks off August 17th at Jones Beach Amphitheater in New York and includes stops at the Hollywood Bowl in Los Angeles (where the band last performed a sold-out show on their wildly successful 13 world tour in 2014), Chicago, Philadelphia, Toronto, Detroit, and Dallas, among others, before wrapping September 21st at AK-Chin Pavilion in Phoenix, AZ.

The massive 2016 world tour by the greatest Metal Band of all time marks The End for Ozzy Osbourne, Tony Iommi and Geezer Butler as they close the final chapter in the final volume of the incredible Black Sabbath story with this tour. Black Sabbath's The End farewell tour promises to surpass all previous tours and will feature the band's most mesmerizing production ever. An updated video announcement can be found below.

When this tour concludes, it will truly be The End, The End of one of most legendary bands in rock 'n roll history... Black Sabbath.
