"In a musical background composed of heavy riffs alternating with progressive scales and with different atmospheres or steps organized throughout the song, "A las puertas" (At the gates) speaks of the arrival at the end of the "Montaña Roja" (title of the album which means red mountain): a road traveled by the one who follows his destiny among the fog and the rugged rock to ascend on his way to the summit. The song poses the culminating moment of the album by condensing its musical and conceptual essence. For this reason, among the 9 songs that compose the upcoming album, perhaps this is the ideal one to present this particular musical proposal".
