Whether that was Omar manic wailing on his guitar, or Ximena's soulful vocals, but that isn't quite felt here.
As surprising as it is to hear Omar sing on this album, he isn't well-developed as a vocalist and that's because he has not had much practice.
Un Escorpión Perfumado features Omar trying to fuse that improvisational atmosphere with a pop-musical structure.
I suppose it's his way of combining the best of both worlds so as to satisfy his fans, regardless of what era in Omar's music they're fond of.
There are no lengthy Jazz-influenced improvisations here, the songs have a much more Pop-influenced traditional structure.
