More than a year-and-a-half after Black Sabbath first announced their reunion, the blueprinters of heavy metal have finally begun their invasion of North America. Sabbath will be stateside until September, and the band started off the long-awaited tour in Houston, Texas last night (July 25).

On November 11, 2011 (11-11-11), Black Sabbath announced that the band's original lineup, Ozzy Osbourne, Tony Iommi, Geezer Butler and Bill Ward, would embark on a world tour and begin writing a new album. Unfortunately, Black Sabbath ran into unforeseen issues before either event was able to begin. Drummer Bill Ward abandoned Sabbath's plans after contract disputes were unable to be resolved and guitarist Tony Iommi was diagnosed with lymphoma shortly after the 11-11-11 announcement.

Although Black Sabbath's plans were stalled, the band's first album in 35 years to feature Ozzy, Tony and Geezer, '13,' was released in June of this year and gave Black Sabbath their first No. 1 debut in the United States. With that success already cemented in the group's history, Sabbath have finally hit the road in North America for a full-fledged tour.

Sabbath performed a set jam-packed with classics last night in Houston, unleashing songs such as 'Iron Man,' 'War Pigs' and 'Paranoid.' The act brought out some new '13' material as well, playing 'God is Dead?,' 'End of the Beginning,' 'Methademic' and 'Age of Reason.'
