Marilia Andrés Casares (born 17 December 1974 in Cuenca) is a Spanish singer-songwriter.
Since she was a child, she showed a great interest in music and in the last course of high-school, she met Marta Botía, with whom she created the successful group Ella baila sola. They performed in several parks in Madrid until they recorded their first album in 1996.[1] They split up in 2001. However, in 2021, the duo (original members Marta y Marilia) reunited to perform a few live concerts in celebration of their 25th anniversary.
