VIDEO: Watch The Piano Guys Mashup Adele's 'Hello' with Mozart's 'Lacrimosa'

As fans of The Piano Guys might have expected, the group has released their own cover of Adele's latest #1 hit, "Hello." What fans may not have expected, is this cover involves no piano at all.

Entitled, "Hello/Lacrimosa," the cover features a cello, arranged to combine the Adele song with "Lacrimosa" from Mozart's "Requiem." Check out the new music video!

In the words of "the guys" themselves, "Hello/Lacrimosa (or "Chello," as it has affectionately been called in the studio) is a musical experiment bridging 18th century spiritualism and 21st century secularism. Imagine Mozart and Adele in the same room in an intense co-write session, quill and pen in hand, respectively. Picturing this hypothetical hangout helped to spark the creative combination of the two."

They go on to explain further how the two songs fit perfectly together,

Haven't heard "Lacrimosa" from Mozart's Requiem? It is a powerful piece of music. Listen here:https://www.youtube.com/watch?v=mhYCa...

As you can hear, both tunes' divergent traits presented challenges. One wallows in a wide, painstakingly minor 12/8 time and the other drives a poignant bi-polar major/minor common time. One draws its power from the fullness of a grand chorus and orchestra, the other from the isolation of a lone voice and piano. One conforms to age-old counterpart canon and musical theory, while the other is conveyed via verse/chorus pop song parlance. However, they share the same fundamental feeling -- "Lacrimosa" (meaning "weeping" or "tearful") mournfully bemoans spiritual death, while "Hello" gripes about relationship regrets. Different centuries. Different realms. Same emotion. Perhaps we aren't as far from our predecessors as we think we are.
