Dubbed as the first heavy metal band, Black Sabbath truly lived up to their dangerous image in the 1960s. However not all of their songs were heavier metal than contemporary greats Led Zeppelin and Deep Purple. The opening riff of ‘N.I.B’, (named after the shape of drummer Bill Ward’s goatee beard, a shape which the rest of the band thought resembled a pen nib) is a warm, downtuned tone that Sabbath guitarist Tony Iommi and other guitarists used in later years.
