Indie Rock lends itself perfectly to the a cappella genre for multiple reasons.
The style naturally beckons a lead to emote during multiple refrains of a given song, while allowing for surreal blending opportunities for the backing group.
Case in point, this cover of The Lone Bellow's "You Never Need Nobody" by the UVM Hit Paws.
BTW, the power behind this soloist's voice is on another level. Enjoy.
