Ever since Nikolai Rimsky-Korsakov wrote “Flight of the Bumblebee” for his 1900 opera, The Tale of Tsar Sultan, it’s been used to show how fast someone could play an instrument. Basically, it’s speed metal for the piano.
Many musicians have taken up the challenge over the last century. According to the edition of Guinness of Book of World Records I consulted, the fastest guitar version clocks in at 620 BPM. If that’s true, then this dude obliterated that record.
