Classico comes from Tenacious D, the comedy rock duo of Jack Black and Kyle Gass, and appears on their 2006 album The Pick of Destiny. The track stitches together famous classical passages, including music by Bach, Beethoven and Mozart, reworked for two acoustic guitars and theatrical vocals. Short excerpts later circulated on streaming platforms as alert sounds, where the dramatic classical playing made an ideal ironic fanfare for donations. This 30 to 40 second section became a recurring donation sound, kept alive by streamers who want a grand, recognisable cue for audience support.
