With the intention of exploring new musical paths, Sabina sought a more eclectic proposal for Esta boca es mía. The album is characterized by a notable variety of styles and influences, and by the collaborations of prominent figures such as Rosendo Mercado and the renowned Cuban singer Pablo Milanes. Clear influences of rock 'n roll can be appreciated in some tracks, while others lean towards Latin music, incorporating elements of salsa and bolero. Four singles were released from this work. The first and perhaps most emblematic, Por el bulevar de los sueños rotos, became one of Sabina's most representative pieces. The song, which evokes a strong Mexican spirit, was conceived as a tribute to Chavela Vargas, whom Sabina considered an influence. It makes references to artists such as Frida Kalho and Diego Rivera, and to elements of Mexican culture. The music video for this track, directed by Juanma Bajo Ulloa, also recreated a typically Mexican atmosphere.
Another standout track from the album is Esta noche contigo, a love song that opened the album and was released as the second single. Although it was well-received, it did not achieve the popularity of Por el bulevar de los sueños rotos. The third single was El blues de lo que pasa en mi escalera, a hard rock piece with a peculiar narrative where the singer recounts past and present stories of people from his childhood with whom he still maintained contact. The central themes of this song revolve around romantic relationships, financial ruin, and the undeserved rise of some individuals. The album was recorded at Cinearte Studios in Madrid under the Ariola label, and drew on genres such as hard rock, pop rock, country, and salsa, showcasing the sonic breadth Sabina sought at this stage of his career.
