For the definitive review, you couldn't do better than CvaldaVessalis's here: "Are We Really Living Or Just Walking Dead Now..."
I won't repeat what my friend has already said. I'll move on to my impression and views.
All the way through, I kept thinking, 'prototype Prince', but on returning home and listening to his first few albums, actually, Janelle Monáe has more going on for her than he did when he began.
Without a doubt, her music is informed by George Clinton's parliament / p-funk, just like Prince. Her music is soul and funk, just like Prince. She moves and dances ... just like Prince! But her set is not as polished as it was in his heyday when I saw him near the end of the 1980s. No one is power-dressing and there's no Cat or Sheila E. Instead, there are a few rather cute, not brilliant (borderline bad) dancers who make it because they're so sixth form. And she's dressed in her forever black and white.
