You may recall cdza (short for Collective Cadenza) from their three-minute tribute to whistling or their jovial piano rendition of Jay-Z and Kanye West’s song, “Niggas in Paris.”

In their latest video, the group sings “What a Wonderful World” in 16 different music genres, transitioning from Gregorian to metal to disco, and even the accursed dubstep.
