Part of the idea for Lilith Fair came out of Sarah McLachlan being told by promoters that you couldn't organise a concert and have a female main act preceded by a female warmup, nobody wants to hear two female bands in one night. This does not apply to male bands, of course. She proved them wrong by putting female groups all together in the festival and it was a success. She has an ego and so do an awful lot of male performers. It does them very well in getting onto the stage and in front of others. She used what she had to get others into the limelight with her.

Men and women are neither more nor less generally musical than each other. There are still quite likely more mediocre male musicians getting airplay and public space than mediocre female musicians, but I think its changing.
