Sabotage

Sabotage is the sixth studio album by the British heavy metal band Black Sabbath, released in June 1975.
The album is a mix of heavy, powerful songs such as "Hole in the Sky" and "Symptom of the Universe", and softer experimental songs such as "Supertzar" and "Am I Going Insane (Radio)", which are similar to the band's previous album. The title of the latter caused some confusion due to the "(Radio)" part, which led people to believe the song was a radio cut or radio version. However, this is the only version of the song: the term "radio-rental" is rhyming slang for "mental". The song itself is very different from the typical Ozzy Osbourne-era Black Sabbath song. It features no heavy guitar riff; instead, a keyboard riff is prominent. The song concludes with an "insane laugh" which carries into "The Writ".
