Just from your list I only am aware of Bjork and Death Grips. Bjork is interesting but I would consider death grips the greatest troll on the planet. You could make an album of a man screaming over banging pots and pans and achieve the same level of avant garde notoriety he has. It's not good in the same sense post-modernist art is not good. It's meaningless noise searching for meaning.
Anyway I keep getting downvoted for this which is hilarious. It's obvious people have virtually no idea what musical talent sounds like. Talent is not what you like, it's legitimate hard earned skill. Sampled trash and top 40s 4x4 beats augmented by auto-tune and filters is not skill no matter how much lipstick you put on the pig. Neither is shouting into a microphone behind overdriven noise-music. Being avant garde also doesn't imply skill, the relationship is not a bijection.
