Sorry, that just doesn't make sense to me in 2027. As if there is a lack of them. There are plenty of female artists/bands touring. If no one in those boardrooms makes an issue of it, nothing will change.
Are the announced names all fine names? Certainly. For every act (except MA, sorry), you can make a point as to why they deserve to be there. And there will undoubtedly be more added... But of the 7 announced headliners (Muse, Fender, Tame Impala, Massive Attack, Turnstile, Sombr, and NBT), I find one woman: the guitarist from Turnstile.
Edit; two, Brooke Bentham does vocals in Fender's band.
