This EP is really a minor work in Soda Stereo's career.
Recorded in September of 1989 it contained only one new song "Mundo de Quimeras" while the rest of the material was integrated by three songs extracted from the previous LP, Doble Vida, but in alternate versions.
"Mundo de Quimeras" is the nearest to the Latin rhythms that the band has played in some time.
This song helped to sell the EP, along with Lenny Pickett's arrangements.
The rest is a reworked version of "Languis," and remixes of two strong songs, the obscure "En el Borde" and the hit "Lo Que Sangra (La Cúpula)." Just for fans and collectors.
