This list is exclusive to rock-descended music. My knowledge of jazz and contemporary classical is less comprehensive than my knowledge of rock and its descendents, so I’m less able to tell what is genuinely new for jazz and contemporary classical.

And no, I don’t know why the artists named above all begin with a letter in the first half of the alphabet.
