La Boîte à Frissons

The Gay and Lesbian Dance on Friday and Saturday evening The idea of this dance is to organize a merry mixing of genders: so gays, lesbians, non-homophobic heterosexuals, of any age, mix together and dance on any kind of music, from accordion music to Dance Music, visiting all musics of the world, pop or disco (in fact, any music, except Techno Music).
