Black Sabbath's debut album was released on Friday the 13th, February 1970.  The self-titled album was a commercial success, but it was not popular with critics.  If fact, Lester Bangs dismissed the album in a Rolling Stone review as "discordant jams with bass and guitar reeling like velocitised speedfreaks all over each other's musical perimeters, yet never quite finding synch". Obviously Sabbath was doing something right, because the album sold in substantial numbers despite being slammed by critics, giving the band their first mainstream exposure.
