On their eighth studio effort, Guadalajara`s Mana continue to evolve their hard rock sound, bringing in influences like the Foo Fighters and pop. The latter influences the lead-off single, "Lluvia al Corazón," a number that doesn`t hit as hard as usual when it comes to guitar and drums, but the emotional weight is very heavy and communicated beautifully. Opening with a mournful harmonica, "Amor Clandestino" is Mana at their most wistful while "Sor Maria" utilizes a drum machine and a sample of monks chanting for one of the more "produced" numbers in the band`s entire catalog. Mana`s growth might not be to every fan`s taste, but with the same heart and same conviction as always, this mature and sometimes softer effort feels like a natural progression.
