Frank Ocean.
Coldplay and Gorillaz also come to mind however I haven't been into the Gorillaz recently.
Kid Cudi's Man on The Moon 2 was great.
Well jeeze...since 2000.
There's way too many bands and artists that I'm thinking of and 3 rappers are on my head too.
I really don't know right now but I do think Frank Ocean is great.
