I don't know any personally but here's a few I know of, off the top of my head! Indigo Girls Tegan and Sara Ani DiFranco Le Tigre Baths Carrie Brownstein ( Sleater-Kinney & Wild Flag ) Frank Ocean Oh man, I almost forgot about Scissor Sisters - if you're into electro-pop then you'll love Invisible Light.
I had some of these, but more I totally missed! Didn't realise Baths was LGBTQ, that's awesome. And Frank Ocean was a huge oversight on my behalf. Cheers!
I listened to Obsidian a bunch of times and was so sucked in by how beautiful it was and how great the lyrics were, it didn't even strike me until make the 20th time listening to Incompatible that he was clearly singing about his first boyfriend. It's the first line of the song even. I completely missed it though.
