After a four-show tease, Black Sabbath have confirmed a full 20-city North American tour. The trek will kick off in Houston, TX on July 25 and will include shows in Philadelphia, Boston, Chicago, San Francisco and other major markets, along with the previously announced stops in Holmdel, NJ, Los Angeles, Seattle and Toronto, ON. Beginning today, fans can click here to RSVP for early access to presale tickets available Thursday, May 2.

Black Sabbath launched their world tour on April 20 with two shows in Auckland, NZ. They are now in Australia for performances in Brisbane, Sydney, Melbourne, Perth and Adelaide, before heading to Tokyo for the first-ever Ozzfest in Japan on May 12. Their current tour previews their new album, 13, which is due out on June 11. As a throwback to their sprawling ’70s sound, five of the album’s tracks are over 8 minutes.
