Released on Sept. 18, 1970, Paranoid is Black Sabbath’s second studio album and is one of the most influential heavy metal albums. Lead vocalist Ozzy Osbourne is known as one of the most famous metal singers in the history of the genre. Originally, Paranoid was titled War Pigs, based on the first track of the album. However, the name was changed because the producers were afraid it would get major backlash from supporters of the Vietnam War, which was raging on at the time. Paranoid was involved in many controversies, including some people's belief that the music was “satanic”, as well as the obvious anti-war messages.  Some of the most famous Black Sabbath songs come from this record, including “Paranoid,” “Iron Man,” and “War Pigs.”

The opening track of Paranoid, “War Pigs” (often labeled as “War Pigs/Luke Wall” on certain streaming services), was originally the self-titled track. “War Pigs” starts off slow; the high-pitched humming of a distant air raid siren blares in the background. The track was originally titled “Walpurgis”, referencing the European holiday, Saint Walpurgis Night, and how it is often associated with witchcraft and satanism. “The song was written as 'Walpurgis,' which sounds a little like 'War Pigs.' But 'Walpurgis' is sort of like Christmas for Satanists. And to me, war was the big Satan' ”, Geezer Butler said in an interview with music blog website, Noisecreep. “War Pigs” is meant to be used as an insult, directly referring to those who profit from war, with Ozzy Osbourne writing lyrics meant to describe those people as satanic and evil, like “Generals gathered in their masses/Just like witches at black masses”. “War Pigs” has a heavy and rough instrumental. The lead guitar has an almost dirty tone that works perfectly with Ozzy Osbourne’s unique tone.

Flipping a full 180 from the last two tracks, “Planet Caravan” is a dreamy, psychedelic-esc song, consisting of congos, flutes and the shaky, echoed vocals of Ozzy Osbourne. This song was such a switch-up from what Black Sabbath was known for, and it has confused many reporters over time, who did not realize that a heavy metal band such as Black Sabbath could pull off something that sounded eerily similar to a Pink Floyd Song. This seemed to be a turning point in Black Sabbath’s musical career. It proved that they could produce both heavy metal and the psychedelic, dreamy sound that “Planet Caravan” provided.

The 1970s were the peak of the Cold War between the United States of America and the Soviet Union. The nuclear crisis was rampant, with both sides having enough explosives to destroy everyone on Earth. “Electric Funeral” was about that fear, the fact that the lives and deaths of all people on planet Earth were in the fingertips of a bunch of military commanders. Black Sabbath was not the first in the music industry to comment on the nuclear crisis, but they definitely popularized that message. “Electric Funeral” switches between slow and harsh segments and fast, almost zippy spots, where Ozzy Osbourne is almost yell-barking into the microphone. The song itself, even ignoring lyrics, could be an analogy for the nuclear crisis. The slow parts are like the calm spots in the Cold War whereas, in other spots, everything seemed fine. Then, the instrumentals all switch up in an instant, referencing events such as the Cuban Missile Crisis, the Vietnam War, or even many of the false alarms in the USA.

In an interview with Grunge, Butler mentions the real meaning of “Hand of Doom”: "Instead of going back to America, they'd have to have a half-way house and there was one in Germany and one in England.” Many American soldiers who saw the horrors of the Vietnam War started using heroin, which was a common phenomenon at the time. The lyrics in the second verse of “Hand of Doom” only back this up more: “First it was the bomb/Vietnam napalm/Disillusioning/You push the needle in." In that same grunge article, Butler talks about experiences with these soldiers, and how bad of a crisis it was. He states, “We go talking to the soldiers and they were in a terrible state and telling me that a lot of them were doing heroin”.  The United States Department of Veterans Affairs did a study on this, and they shared that over 43% of soldiers used heroin, with over half becoming addicted.
