Ylvis is a revue group of brothers Bård Ylvisåker (b. 1982) and Vegard Ylvisåker (b. 1979). The musical brothers originated from Sogn, but grew up in Bergen and Africa.

The brothers debuted professionally on the 19th October, 2000 at the Ole Bull Theater in Bergen with the show "Ylvis - en kabaret".

In connection with the show was the song "Rumor says" recorded, pressed as a CD-single, and sold during the show, but was never put out for regular sales.

In 2001, after the Norway tour with "Ylvis - a cabaret", Ylvis's main characters performed in the Grieghallen with the Bergen Philharmonic Orchestra in a concert called "Ylvis goes philharmonic". That same year debuted Bård and Vegard on TV as regular guests in Rune Larsen's "Absolutt norsk" on NRK. In 2002 NRK added Ylvis as an element in Trond-Viggo Torgersens "TVT".
