Some of heavy metal's biggest names are reportedly joining forces for a tour this spring. Ozzy Osbourne, Judas Priest and Motörhead have confirmed one date in Brazil directly following the Monsters of Rock Festival in April. According to the production company Hits Entretenimento, the three acts will hit the road on the Monsters Tour, Pollstar reports.

Osbourne will headline the festival April 25 in addition to Motörhead, Black Veil Brides, Rival Sons, Coal Chamber and Primal Fear. Kiss is slated for the headline spot the following day with Manowar, Accept, Unisonic, Yngwie Malmsteen and Steel Panther. Judas Priest will join in on both days.

The first date of the Monsters Tour is April 30 at Porto Alegre's Zequinha Stadium. No further dates have been announced.

Previously, the Prince of Darkness has linked up with both acts. He shared the bill with Judas Priest at a concert in Canada in 2008. Lemmy and the boys joined Osbourne on the Blizzard of Ozz tour in the early 1980s, Ultimate Classic Rock notes.

Osbourne is currently working on music with Black Sabbath. The band will release one more album and go on one more tour in 2015. The health of Tony Iommi is a concern, though: He was diagnosed with lymphoma during the recording process of 13. The frontman is also working on solo material to follow up his greatest hits collection Memoirs of a Madman.

Judas Priest released their 17th studio effort in July. Redeemer of Souls hit No. 6 on the Billboard 200 chart.

Motörhead put out its 21st album, Aftershock, in 2013. It did not chart in America, but did well in Finland and Germany.
