Dog & Butterfly is the fourth studio album by American rock band Heart. It was released on October 7, 1978 through Portrait Records. Heart rebounded from their legal dispute with Mushroom Records over the release of the platinum-selling Magazine in April 1978, as Dog & Butterfly was certified double platinum, spent 36 weeks on the charts, and peaked at #17 on the US Billboard 200. The album was the 'proper' successor to 1977's hit Little Queen in terms of musical development and direction, and contained two hit singles: "Straight On", and "Dog & Butterfly".
As Heart themselves noted on the album's release, side 1 was the "Dog" side, and was the more "rocking" compared to the "Butterfly" side 2, which was all ballads, with the exception of the closer "Mistral Wind", which, in many ways, epitomized the trademark sound for which Heart would be remembered: folksy ballads shifting into searing hard rock explosions.
Though the first song on the album, "Cook with Fire", sounds like a live recording, it was actually recorded in the studio. Audience sounds were overdubbed on the studio recording from a live performance, although the liner notes say it was recorded live in Memphis, so this is debatable.
