Hombre, Tierra y Alma shows a more mature band with more diverse songs. The acoustic guitar is featured more prominently, and the obligatory prog instrument, the flute, is even used on a track. The two guitarists complement each other better on this album too. On the debut, a lot of the double guitars were straight harmonies that one person could have overdubbed. On Hombre however, they tend to be playing completely different parts more. I'd rate this album up there as one of the best Spanish prog rock albums from that era, with their first quite a ways behind, but still worth a listen. Those fond of Crack, Nu, as well as the other heavier prog will enjoy Bloque. My primary complaint about Hombre is that it appears to have been mastered from vinyl! Although they clearly used a relatively clean copy, there are many spots where clicks and pops can be heard. Overall though, it's not that noticeable, and worth putting up with for the quality of the music.
