I have been listening to this album many times and I can understand the mixed reviews. Many people are disappointed with the new Gotan Project album. In my opinion most of them were awaiting for something new and innovating, because the band was very innovative from its beginnings. Lunatico set the bar quite high. However, I see Tango 3.0 as a consolidation of their work. They know what they do and this album is really well-crafted. You will not discover any new sound (in the end it is tango, everyone knows how tango sounds). Furthermore, some of the songs in Tango 3.0 remember us to their previous records "La revancha del tango" and "Lunatico".
