Dionysos is a French pop band that originated in Valence, Drôme, in 1993; their formation took place at their lycée.

In 1999, they signed a deal with a major label (the now defunct Trema) and released Haïku, which propelled them into the public eye, largely owing to the success of the single "Coccinelle."

Many of the songs carry a surreal quality, with a significant number featuring nonsense lyrics, such as the track "Surfin Frog."

The lead singer, Mathias Malzieu, is also working on other projects such as the career of Olivia Ruiz (his partner from 2005 to 2011), and his other hobby : writing (published 4 books in 2002, 2005, 2007 and 2011).

Babet has begun a solo career and released two albums: Drôle d'oiseau (5 March 2007) and Piano Monstre (27 September 2010).
