The number 88 represents the number of keys on a piano, which is a reference to the musical talents of Buckaroo Bonzai and his band.
Buckaroo Bonzai is the main character in the 1984 cult classic film "The Adventures of Buckaroo Bonzai Across the 8th Dimension." His band, The Hong Kong Cavaliers, is made up of a group of his friends and fellow scientists who also happen to be skilled musicians.
The name is a nod to Buckaroo Bonzai's diverse cultural background and his love for adventure. The "Hong Kong" portion represents his Chinese heritage, while "cavaliers" refers to his daring and risk-taking nature.
While the band is fictional, the actors who portrayed Buckaroo Bonzai and his band members are all talented musicians in real life. They even released an album under the name "The Hong Kong Cavaliers" in 1984.
The band's music can best be described as a mix of rock, new wave, and science fiction themes. It has been referred to as "nerd rock" and has gained a cult following among fans of the film.
