“Giddy Gorilla” is the music to an imaginary heist movie trailer playing in 11 Acorn Lane’s heads. It features a cocky baritone saxophone, cheeky bongos, a pounding floor tom, tricky timbales, shrewd guitars and cunning cornets. All conceived, concocted and contrived in the covert confines of the subterrestrial vault we call “The Armory” that harbors our euphonius arsenal. Will “Giddy Gorilla” break the bank? Unlikely. But it’s hell-bent to come to a streaming service near you.
