This video of Florida State University's Acabelles singing Lorde's "Royals" is a couple weeks old, but it's still worth posting on the off chance that you missed it. Man, is there anything more uplifting than a cappella? That was a rhetorical question of course because duuuuh, there is nothing more uplifting than a cappella (and yes, I AM well aware that putting that on the record might mean that no one will want to have sex with me ever again).
The 'percussion'/'beat' people in a cappella is always the most amazing to me. A lot of people grow up singing and taking classes, etc., but I feel like their roles are usually self taught (maybe I'm wrong!) and such MAGIC. Looking at their lips move and figuring out how they sound exactly like a set of drums is crazy to me.
