"Classico" is the second song in Tenacious D's 2006 film Tenacious D in: The Pick of Destiny, as well as the movie's soundtrack album. The song, as featured in the movie, is an exploration of classical guitar music in aid of proving Kyle Gass's musical prowess to Jack Black. In it, Gass plays sections from Bach's Bourrée in E minor (from Suite in E minor, BWV 996), Für Elise by Beethoven and Eine Kleine Nachtmusik (Serenade in G Major, K. 525: I. Allegro) by Mozart.
