The compositions of Mediterráneo bear the signature of Joan Manuel Serrat, with the notable exception of Vencidos, whose lyrics are inspired by a poem by León Felipe. The album's sound was shaped by the arrangements of Juan Carlos Calderón, Gian Piero Reverberi, and Antoni Ros-Marbà, who were also in charge of musical direction alongside Calderón and Reverberi. Among the standout songs on the tracklist, we find the title track, Mediterráneo, and Aquellas pequeñas cosas, which have become pillars of his repertoire. The song Lucía is also an important reference point within the work.
The legacy of Mediterráneo extends over time. In 2004, on its twentieth anniversary, the publication Rockdelux placed it third on its list of "the 100 best Spanish albums of the 20th century." This recognition underscores the album's relevance in the musical history of Spain. Later, in 2007, Mediterráneo was included in the Latin Grammy Hall of Fame, an honor that consolidates its impact. After a period when the album was out of print, it was reissued in 2000, allowing new generations to discover its sound.
