The sound of Vasos y Besos diversified, showing different facets. There are tracks with a Brazilian feel, like No se desesperen with its samba touch, and others more disco-oriented like Sintonía americana. There is also space for hard rock in Así es el calor, the new wave energy of Vamos al ruedo, and the reggae of Chalamán. Miguel Abuelo's lyrics shine brightly in compositions like Yo soy tu bandera and Espía de Dios, and Mundos in mundos is added, a piece that came from early demos by Miguel. Calamaro's songs also played a key role in connecting with a wider audience, without neglecting the quality that always defined the band.
The song Mil horas, included in this work, had its own very distinguished journey. In 2002, Rolling Stone placed it 14th on its list of the 100 Argentine rock hits. Later, in 2007, Rock.com.ar ranked it 77th in a similar ranking, and in 2006, Al Borde recognized it among the 500 best Ibero-American rock songs, at number 38. After the album's presentation at Vélez Sarfield, Daniel Melingo left the lineup to focus on Los Twist, and his place was taken by Alfredo Desiata.
