"distinctive fusion of piano-driven schizoid pop and lyrical uplift." is what they're famous for i guess.(ty google) I can't really think of a genre they fit into.. alternative/alternative rock maybe? They have 3 albums, one is self-titled (Twenty One Pilots), there's Vessel, and Blurryface. I've listened to all of them and I'm in love with Blurryface right now. Twenty One Pilots is a good album, but Vessel has a lot of their most famous songs (car radio, house of gold, Migraine, Ode to Sleep, Holding On to You).
I'm just a little obsessed lmao
