Omg my time has come!
Here to introduce everyone to my favourite singer Nina Hagen - she's officially gender critical and involved in the Detransitioners Alliance, which I think must be a first for a big music personality!
She's a German classically trained soprano with a vocal range of about six octaves (!) who branched into a punk career in the late 70s - many know her as the Mother of Punk - and has also dabbled in gospel, disco, progressive-ish rock, and Hindu mantras.
A lot of her most interesting music is in English as she lived in the USA for a while, but she never really made it in the West as IMO she should have (she's always had a devoted circle of gay fans though). I'd love to see a gender-critical renaissance of her work! Obviously it varies a lot in genre but it's all extravagant, satirical and absolutely hilarious.
Her most typically feminist song is originally in German but I'll put a translated bit here - 'Unbeschrieblich Weiblich' (Indescribably Womanly):
'Marlene had another plan
Simone Beauvoir said: God Forbid!
And before the first children's cry
I must free myself first
And momentarily I feel
Indescribably female
Why should I fulfill my duty as a woman?
For who?
For them?
For you?
For me?
I don't feel like fulfilling duty
Not for you
For for me
I have no duty'
Going to post links to my favourite live performance and my favourite English song from her, let me know if you'd like more recommendations because I honestly know her discography like the back of my hand at this point 
. I only got into her music in mid 2019 so it was a nice surprise to hear about her GC beliefs a few months later!
