You may have noticed a peculiar sound ricocheting through pop music recently: a springy sort of trilling noise, the kind of thing you could imagine being used as a sound effect in a Woody Woodpecker cartoon, perhaps one involving pogo sticks.
You know what I'm talking about? No? It's like a hyena with hiccups, maybe, or a chicken being tickled, or a castrato dangling from a bungee cord. No? OK, have you seen Amadeus? It also sounds a little like Wolfgang's laughter in that, which in turn sounds a little like Tiny Tim's cackle in "The Viper". If we really want to go out on a limb, you could even compare it to Jello in a hurricane, which is a thing Tiny Tim sings about in "Tiptoe Through the Tulips". Which is to say it sounds a little giddy; a little loony, even. But we're getting ahead of ourselves.
In any case, that sound is all over the place lately. It turns up in Rustie's "Up Down", off the Glasgow producer's new album Green Language, and it plays a major role there, too, setting up a manic sort of call-and-response pattern with D Double E's cry, "It's gonna go down!" (Buh-loo-bi-dee-doo! Buh-loo-bi-dee-doo!) The sound recurs every two bars, like a cuckoo clock on speed. By the end of the song, we will have heard it 62 times.
