N.I.B.
Black Sabbath
"N.I.B." is the closest Black Sabbath get to blues on their debut — Geezer Butler's intro bass solo establishing a groove that actually swings before Iommi's riff arrives and grounds it in something heavier. The initials reportedly stand for "Nativity in Black," though band members have offered contradictory explanations. Lyrically it's sung from Satan's perspective, a love song from the Prince of Darkness to a mortal — a conceit that's simultaneously absurd and genuinely unsettling, the sincerity of the delivery making the joke darker than it intends to be. Osbourne's vocal has more range here than elsewhere on the album, the melodic line asking something of him. Production-wise it sits between blues rock and something genuinely new, the rhythm section generating enormous weight without losing musical shape. Best heard as evidence that Sabbath had a sense of humor — dark, yes, but present.
