Some songs tend to have an evident rock 'n roll flavour while others have a much more Latin influence with styles such as salsa and bolero. In fact, Esta boca es mía is known for its variety of styles and influences and for the collaboration of various important music personalities such as Rosendo Mercado and the prominent Cuban singer Silvio Rodríguez. In order to produce the album, the singer felt the need of doing something different from his previous musical experiences and decided to create something more eclectic. Īs in the rest of his albums, Joaquín Sabina found the inspiration for the tracks in his personal experiences, such as his paternity, his recent divorce form his former wife Isabel Oliart, his life in Madrid and also his frequent trips to Latin America. For that, as always, the performer not only teamed up with his fellow collaborators, Pancho Varona and Antonio García de Diego, who would arrange the most of the songs, but also, started counting with the help of a new collaborator, Olga Román, a jazz singer who had previous experience in composing and performing jazz songs live and who would turn into Sabina's back vocal since then, till 2009, when she restarted her solo music career. In the mid 1990s, Sabina was in his personal and professional maturity and found himself in the challenge of producing an album that could be at the same level or better than Física y química.
