Something he hasn't changed much is his simple style. He likes the sound of his guitar, and he makes sure his voice floats right over it, but I think that just the same he's managed to greatly improve the quality of his overall sound.
Give him a try.
Translated to "The Plot and Outcome", the song is essentially, in a romantic sense (and he repeats this several times) loving the plot more than the outcome.
You can hear this without understanding or paying attention to the lyrics. The melancholic harmonica against the more cheerful guitar, all accompanied by the wind instruments. It's really excellently done.
If you enjoy the sounds, you should look into the rest of the album, Amar la Trama (Loving the Plot).
For the most part the album is about as simple and easy to listen to as today's track, but there are a few songs here and there that are more vocal based. Some examples could be La Nieve en la Bola de Nieve (The Snow in the Snowball) or Aquiles Por Su Talón es Aquiles (Aquiles By His Heel is Aquiles).
Just the same he can switch up and let the voice take the second role, a bit like today's track but more like Mundo Abisal (Nether World).
Overall a decent listen. I'm sure by the time the next album is released the quality will increase, he's done a great job of it so far. Until then, this album is gonna get its fair share of my ear.
