Joan Jett's androgynous look was inspired by Marc Bolan.

The 61-year-old musician says Bolan - who was the lead singer of T. Rex and one of the pioneers of the glam rock movement of the 1970s - inspired her music and image.

Joan - who appears on Hal Willner's final project, a collection of Marc Bolan/ T. Rex covers called 'Angelheaded Hipster', where she performs 'Jeepster' - told Variety: ''Hal and I were both big T. Rex fans and Marc Bolan was my first crush.

''That's his scream I'm letting flow through me [in 'Jeepster'], but it's also intrinsic to what I do. I don't even think about it - it's part of me. Marc Bolan had a major impact on every aspect of my musician self, especially the look - the androgyny.

''The lyrics are surreal, and the words just sound beautiful together. They probably make sense to him, but if you're looking for a message, you have to create your own. I enjoy the sound, the music and the melody for its own sake. It doesn't even have to get any deeper than that.''

Meanwhile, Joan - who was inducted into the Rock and Roll Hall of Fame in 2015 - previously slammed the music industry as ''nasty'' and said it was extremely tough to break into as a young woman in the 1970s.

She said: ''Extremely tough. Just the level of ... [people] not giving you a chance right away. Looking at you as a joke, as 'it's kinda cute'.

''And then people would get very nasty. It is like what the Internet is today, [but] people saying it to your face. You're a this, you're a that, you suck, your music's bad. It could get really nasty.''
