Esta Boca Es Mia (1994), Joaquín Sabina's 11th studio album, is one of the Spanish singer/songwriter's most varied of the era.
Whereas prior albums such as Fisica y Quimica (1992) and Mentiras Piadosas (1990) were written and produced in collaboration with Pancho Varona and Antonio Garcia de Diego, Esta Boca Es Mia features numerous collaborations, most notably Álvaro Urquijo on "Por el Boulevar de los Sueños Rotos" and Pedro Guerra on "Ruido.".
