“Which Black Sabbath album was released in 1975 and includes ‘Am I Going Insane (Radio)’?” — The answer is Sabotage. The album was released in 1975 and contains the song as one of its most unusual and debated tracks.
Sabotage was Black Sabbath’s sixth studio album. Released in the United States on 28 July 1975 and in the United Kingdom in September, it mixes aggressive songs such as “Hole in the Sky” with more experimental material. “Am I Going Insane (Radio)” appears late in the original sequence, after “Supertzar” and before “The Writ.”
The word “Radio” in the title is often misunderstood as meaning a radio edit or alternate broadcast version. Bill Ward explained it as Cockney rhyming slang: “radio rental” rhymes with “mental.” The song was also issued as a single in 1976. It is easy to confuse Sabotage with Technical Ecstasy or Never Say Die!, but those are later Black Sabbath albums and do not contain this track.
