H ZETTRIO, the piano trio that delivers music that adults and children can laugh and dance to, will host a showcase event for the music program they host. “SPEED MUSIC Sokudo no Ongaku” is a music program that invites viewer requests for “timeless Japanese classics,” which H ZETTRIO covers with their outstanding ensemble skills in their own arrangements. Since the program began in 2018, it has received high praise, and in March 2026 it was also decided that an album compiling performances from the show, “SPEED MUSIC Sokudo no Ongaku Vol. 11,” will be released. Having established a Guinness World Record in the category “Most digital singles released in consecutive months by a single music unit,” and continuing to unfold activities beyond common sense in dazzling fashion, they will take the stage with nearly 400 songs they have covered on the program. Alongside H ZETTRIO’s music, look forward to a special stage that evokes the changing seasons.
