Lætitia Sadier, French singer and keyboard player
Lætitia Sadier (born 6 May 1968, sometimes known as Seaya Sadier) is a French musician, best known as a founding member of the London-based avant-pop band Stereolab. In 1996, while Stereolab was still active, she formed the side project Monade. In 2009 — the same year Stereolab became inactive — she ended the Monade project and began to perform solo work under her own name; her current band is known as the Lætitia Sadier Source Ensemble. She has frequently performed guest vocals and collaborations with other artists.
