L.E.J

L.E.J, short for Lucie, Élisa and Juliette, sometimes Elijay, is a French band composed of three women from Saint-Denis, a city in Paris' suburbs. They became famous by condensing numerous top songs from the summer of 2015 into a mashup performance. Their song mashup Summer 2015 had millions of plays on YouTube as of August 2015 and was thus a global hit in less than a month. Their music is based on classical and world music, described by MTV reviewer Joseph Lamour as "eclectic".
