Black Sabbath have announced that their as-yet-untitled new album will be released in April 2013. In addition, the band has unveiled dates for their first tour of Australia since 1974.

Ozzy Osbourne, Tony Iommi and Geezer Butler have been working on their first new studio album together since 1978's 'Never Say Die.' Rick Rubin is producing, Ozzy is currently recording vocals, and Butler is writing all the lyrics. Iommi has already finished his guitar tracks. One song title has been confirmed – ‘God Is Dead.’

If their set lists at 2012's Download and Lollapalooza are any indication, Australian fans can expect to hear classic Sabbath songs like 'Paranoid,' 'War Pigs,' 'Iron Man,' 'Snowblind' and many more. And since the  album will be out by then, a whole batch of new songs will probably be played live as well.

The press release doesn't say who will be playing drums on the Australian tour or on the album, as original Bill Ward has parted ways with the band over contract disputes. Ozzy's drummer Tommy Clufetos has been playing with Sabbath, and it would make sense he would continue in that role.

Tickets for the Australian shows will go on sale Thursday Nov, 8. My Live Nation members will have an exclusive pre-sale starting Friday, Nov. 2.
