Black Sabbath - Black Sabbath

The self-titled debut album Black Sabbath was released on Friday, February 13, 1970, in Europe by Vertigo Records. It was later released in the United States in June 1970 by Warner Bros. Records. The Friday the 13th release date was intentionally chosen to align with the album's dark, occult themes.

The album's opening track, "Black Sabbath," is widely considered the first true doom metal song, characterized by its use of the tritone, or "devil's interval." Other heavy, foundational tracks include "The Wizard," "N.I.B.," and "Behind the Wall of Sleep." These songs relied entirely on Tony Iommi's heavily distorted guitar riffs, Geezer Butler's bass, Bill Ward's drums, and Ozzy Osbourne's vocals.

Yes, the band used a rain and thunder sound effect to open the first track, "Black Sabbath," creating a spooky, cinematic ambiance. They also used a tolling church bell to transition into the song. These atmospheric additions helped establish the gloomy, horror-movie aesthetic that became the band's trademark.

Commercially, the album reached number 8 on the UK Albums Chart and number 23 on the US Billboard 200. Despite being heavily panned by music critics upon release, it eventually achieved platinum certification in the United States. Its massive commercial performance helped establish the foundational sound and commercial viability of heavy metal music.
