Big fucking deal. If people are worried about preserving her 'he' voice, they'll have half a fucking mind and listen to the older record where they feel safe identifying a singer's gender through their tonal range.
It's gendering that feels safe because it's supposedly been brought into the realm of sex.
Supportive is good, but how has it become a point of worry whether someone 'sounds' like a woman? Old Against Me! (as much as I hated them) records will never go away, and perhaps more significantly, people are somehow jumping on the 'voice is gender bandwagon.' And that one does bother me.
To put my ease with gender/voice/register issue more into perspective, I present 'Boomerang,' by Serge Gainsbourg and reimagined by Etienne Daho and Dani -Found here. My (admittedly entirely personal) favorite example of singing that manages to ignore idiocies like whether someone sounds like a man or a woman.
Personally, I'll Judith Butler this one until the end of the day.
