Tiësto OON (Dutch pronunciation: ; born Tijs Michiel Verwest on January 17, 1969) is a Dutch musician, DJ and record producer of electronic dance music. Although he has used many aliases in the past, he is best known for his work as DJ Tiësto. On his latest productions, however, he has dropped the "DJ" label and is now known simply as "Tiësto", an alias which is a twist of his childhood nickname.
