This is a 2 CD set containing a total of 23 songs composed by Armando Manzanero and　supposedly sung by Armando Manzanero and his guests as duets. However, the songs are too much overdubbed and some sound like somebody (else) making a solo. Worsestill, the packaging is most disappointing, like a counterfeit product --- there's no booklet, no lyrics, not a single sheet of liner notes, not any recording or production dates... which is quite unusual for a regular multi-CD set from Warner Music.
