Watch Adele’s ‘Hello’ Mixed With Mozart in ‘Chello’ Mashup

“Imagine Mozart and Adele in the same room in an intense co-write session.” This is the premise behind “Chello,” a mash-up of Adele’s “Hello” and “Lacrimosa,” a section of Mozart’s Requiem Mass in D.

Known for their renditions of Bruno Mars, “Let It Go,” and more, The Piano Guys revealed their latest performance, which was “created by 100 tracks of acoustic and electric cello” to “18th century spiritualism and 21st century secularism.”

In the video’s description, the group wrote, “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.”

They continued, “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.”

“Chello” (or “Hellocrimosa,” the alternate title) is performed by Steven Sharp Nelson on electric and acoustic cellos, with Al van der Beek on percussion and vocal textures.
