Fellow electronic musicians Romanthony, Todd Edwards, and DJ Sneak collaborated on some tracks both musically and lyrically.

For the album's music videos, the group developed a concept involving the merging of science fiction with the entertainment industry. Inspired by their childhood love for Japanese anime, the duo collaborated with Leiji Matsumoto to produce Interstella 5555: The 5tory of the 5ecret 5tar 5ystem, an anime film with the entirety of Discovery as the soundtrack.

The film features no dialogue, with few sound effects. In the lead-up to Discovery 's release, the duo adopted robot costumes, claiming they had become robots as a result of an accident in their studio. They also launched Daft Club, a website which featured exclusive tracks and other bonus material. Discovery was a critical and commercial success, peaking high across several charts internationally on release. Critics praised Daft Punk for innovating the house music scene in the same manner they had done with Homework.

The album produced six singles ' One More Time' was its most successful, and became a club hit.
