Dog & Butterfly became Heart's fourth million-selling album and placed two songs of opposing styles in the Top 40. Like their Magazine album, Dog & Butterfly peaked at number 17 on the charts, but the material from it is much stronger from every standpoint, with Anne and Nancy Wilson involving themselves to a greater extent. The light, afternoon feel of the title track peaked at number 34, while the more resounding punch of "Straight On" went all the way to number 15 as the album's first single. With keyboard player Howard Leese making his presence felt, and the vocals and guitar work sounding fuller and more focused, the band seems to be rather comfortable once again. Average bridge-and-chorus efforts like "Cook with Fire" and "High Time" aren't spectacular, but they do emit some appeal as far as filler is concerned, while "Lighter Touch" may be the best of the uncharted material. After this album, guitarist Roger Fisher left the band, but Heart didn't let up. 1980's Bebe le Strange showed an even greater improvement, peaking at number five in April of that year.
