Guitarist and songwriter Nancy Wilson is one half of the rock band Heart, along with her older sister Ann Wilson. Nancy and Ann have been the face of the band since the mid-70s. Heart’s first album, Dreamboat Annie, was released in 1976 right as the band was making traction opening for big acts like Rod Stewart and The Bee Gees. Soon their songs, like “Magic Man” and “Crazy On You,” started to take off in the States, and Heart quickly became a headlining act.

Nearly 50 years since their debut album, Heart has experienced career highs—like a string of chart-topping hits and an induction into the Rock N Roll Hall Of Fame—as well as their fair share of personal and professional adversity. Today Ann and Nancy remain steadfast in continuing Heart’s legacy. This month they embarked on a world tour—their first in five years.

To celebrate Ann and Nancy Wilson’s massive contribution to rock n roll history, we will feature conversations with both sisters over the next two weeks. Today we’ll hear Leah Rose talk to Nancy about how the popular drugs of the ‘70s and ‘80s influenced Heart’s sound. She also describes how being accepted by the musicians of Seattle’s grunge scene helped her overcome Heart’s fraught experience recording power ballads in the ‘80s. And she describes the lo-fi setup she used to score the soundtracks of her ex-husband Cameron Crowe’s hit movies: Almost Famous, Vanilla Sky, and Jerry McGuire.
