Kirk Gay brings the soundtrack of Undertale, a hugely popular role-playing video game by Toby Fox, to the world of percussion ensemble with the medley Orchestrations of the Underground. Three themes from the Undertale soundtrack appear including, “His Theme,” “Spear of Justice,” and “Meglovania.” He cleverly weaves these three themes together in one tight-knit, energetic package. Kirk has dedicated this arrangement to his daughter Kenna who first introduced him to this music. This piece comes as a professionally printed and bound score and includes individual parts in PDF format for printing or for tablet viewing.
