twenty one pilots (also stylized as twenty øne piløts, TWENTY ØNE PILØTS, twenty | one | pilots, and TØP) consists of vocalist, pianist, bassist, and ukulele player Tyler Joseph and his best friend Josh Dun, who plays the drums and trumpet. The band’s genre is difficult to define, but best described as indie pop, with elements of rap, hip hop and rock. Fans have proclaimed their own music genre as “Schizoid Pop.”
The name twenty one pilots was inspired by the Arthur Miller play, All My Sons, a play about a man whose choice to send out faulty airplane parts for the good of his business and family caused the death of twenty-one pilots during World War II. The aspect of the play which influenced the band is the moral decisions and consequences that come with everyday decisions. Thus, the band fights the constant battle between man and mental illness.
