1970: Black Sabbath's self-titled debut album is released, timed to come out on Friday the 13th. To add mystique to the band's image, new manager Patrick Meehan asked the band to stop giving interviews. While the album's commercial single, "Evil Woman," failed to chart, word of mouth sold more than 5,000 copies of the album in the first week and the album would eventually climb to No. 8 on the UK Albums Chart. Following its North American release in May 1970, the album reached No. 23 on the Billboard 200, where it remained for more than a year.
