idk if science has admitted this is a fact yet but strong powerful women playing music is sexy & not because of their looks.
It's funny that you posted this, but yesterday I was going to post some of my female favorites. Might as well now.
Joan Jett - the music is a little sugary, but I still love her rebel attitude e.g. "Bad Reputation".
Karen Carpenters - Karen was a great singer and drummer
Beth Gibbons (Portishead) - what a sultry voice
Kim Deal (Pixies/Breeders) - Whether fronting a song like "Gigantic" or "Cannonball" or singing back-up vocals, she's a queen. The Pixies weren't the same without her.
Karen O (Yeah Yeah Yeahs) - Premiere entertainer. Your eyes immediately focus on her whenever the YYYs perform live.
Debbie Harry (Blondie) - Oh man, Debbie/Blondie in the 70s. Ooh la la that New Wave era.
Kim Gordon (Sonic Youth) - Loved her attitude on stage
Victoria Legrand (Beach House) - I grew up on metal, hardcore, punk, etc, but I mellowed out in my old age and Beach House is one of my favorite bands. Victoria has the ultimate dream pop voice.
Sade - Even in my heaviest of death metal days, I had love for Sade, my original queen of sultry songs.
Rachel Goswell (Slowdive) - Funny how I grew up on such heavy music and now I'm old and mellow listening to Beach House and Slowdive. I look at Rachel in her early days of Slowdive and watch her now in her 50s and it makes me think of me. Another great ethereal voice for this kind of music.
I'm probably leaving out a few, but these are my favorites that I can think of right now.
