In 1975, Ozzy Osbourne made a song that annoyed all of Black Sabbath. It was the beginning of his solo career

A Moog-driven song Ozzy Osbourne brought to Black Sabbath during the making of *Sabotage* frustrated his bandmates, who disliked its direction. Drummer Bill Ward later called it a good song and said Osbourne’s personality was emerging in it; the article presents the track as an early sign of the musical independence that would shape Osbourne’s solo career.

The song was “Am I Going Insane”, recorded while the band were dealing with record-company lawsuits and pressure to produce a radio single. The article links its lighter, more melodic character to later solo material such as “Crazy Train”, whose major-key passages helped distinguish Osbourne’s sound from Tony Iommi’s heavier riffs.
