Hide and Seek by Imogen Heap
Combining eloquent lyrics and rich, resonating harmonies, Heap creates a vocal masterpiece, bursting with countermelodies and sky-high notes. The tune and rhythm subtly change within each verse, but the perfect bittersweet tone is what really stood out to me about this piece. This is a wonderful song to top off any playlist. Please give this genius acapella piece a listen, it may redefine what you thought was even accomplishable by music.
