Barracuda

Ann Wilson wrote the lyrics in a fit of rage against Mushroom Records. To drum up publicity, the label had run an ad implying an incestuous affair between sisters Ann and Nancy Wilson.

"You're lying so low in the weeds
Bet you gonna ambush me"

The "barracuda" refers specifically to a radio promoter who asked Ann about her "lover," referring to Nancy. But more broadly, it symbolizes the predatory nature of the record business that sought to exploit them.

Released in May 1977 as the lead single from Little Queen, the song was Heart's response to their legal battles and fallout with their previous label.

The "porpoise" mentioned in the lyrics ("Porpoise said...") is reportedly a nickname for the record company, playing on their logo. It's a scathing diss track before diss tracks were a thing.

The songs signature galloping guitar riff is one of the most recognizable in rock history. Nancy Wilson has admitted it was inspired by the riff from Nazareth's cover of "This Flight Tonight."

The track also features the "flanger" effect on the guitar prominently, creating that jet-engine "whoosh" sound that gives the riff its underwater, menacing quality.

Phrases like "sell me, sell you" attack the commercialization of art. Ann Wilson's vocal performance is legendary—aggressive, soaring, and dripping with contempt for the "barracuda."
