Louis Warynski was born on 6 January 1984, in the French city of
Metz. He entered the local conservatory at the age of six and went on to learn multiple instruments, including the violin and
harpsichord. After graduating from high school, Warynski obtained a master's degree in
musicology. He began working with electronic music, sampled lines by
Lewis Carroll's
Mad Hatter, and adopted the moniker as his stage name. In 2009, the
Nancy-based independent label
Ici, d'ailleurs... released his first EP,
Darling, Darling, Darling... That year, his performance at
Eurockéennes de Belfort won him the Fabrice Ragris prize, awarded for young talent. His next EP, titled
Scandale!, was released in November 2009. In 2010, the artist appeared at
Les Francofolies de La Rochelle and later travelled to Hungary to perform at
Sziget Festival, in Budapest. His debut full-length album, titled
613, came out in 2010. In 2011, Chapelier Fou held a series of performances at the
Centre Pompidou-Metz and later released the EP
Al Abama. In 2012, he took part in the
Celtic Connections music festival in Glasgow, Scotland. The same year, he travelled to Australia and New Zealand to play at
WOMAD. His second studio album,
Invisible, was released in March 2012. He promoted it with a number of shows across Europe, including at a
Nuit Blanche in Paris. He returned to Australia for more performances the same year. Chapelier Fou has since published the EPs
Protest (2014) and
Fuses (2015) as well as the full-length albums
Deltas (2014),
Kalia (2016),
Muance (2017),
! (2017),
Méridiens (2020), and
Parallèles (2020). Between 2014 and 2019, he performed with a group of musicians, including Maxime François (viola, synthesizers), Maxime Tisserand (clarinets, electronics), and Camille Momper (cello), before returning to a solo format in 2020. In 2021, he formed the acoustic group Ensemb7e, which included Grégory Wagenheim (piano), Nicolas Stroebel (drums), Maxime Tisserand (clarinets), Camille Momper (cello), Maxime François (viola), and Marie Lambert (violin ). In 2021, Claire Moret replaced Momper. In 2022, the group released an eponymous studio album. ==Musical style==
