Peruvian rockers, Don Juan Matus continue to expand their musical approach on 'Más Allá Del Sol Poniente' from the more generic stoner riff-rock to psychedelic space rock to elements of avant-garde prog in the vein of King Crimson. What is impressive is each song on this album has its own sound and personality and while the album is horribly short at only 34 minutes, seven out of its eight tracks are instantly memorable. Each track is different and sometimes a completely different style but what is amazing is how smoothly each tune bleeds into the next. These smooth transitions from one style to the next make this album an incredibly satisfying and engaging listening experience and also very mature. Even their more plodding riffing moments have a mature and classy taste to them that gives the album a sense of sophistication.
