One of the reasons why I love nu metal is because you never know what different musical elements to expect in any different artist. Puya takes the groovy nu metal base sound, and blends it seamlessly with funky latin jazz and various kinds of hispanic music. It's probably the only metal album in existence where a conga line could fit right alongside a moshpit.
Throughout the whole album the band is complimenting funky bass licks, thrashing and groovy riffs, fat horns, energetic vocals that switch between hardcore rapping, gang vocals, and some great melodies here and there. It's just so damn fun, and whenever I hear this I wish more metal bands would experiment with the funkier and smoother sides of jazz instead of dissonant improv stuff. Siguelo Pa Llá is by far the most infectious, sounding like a funk metal band collided with an old bossa nova band and came out all the better for it. Bembelé starts out sounding like something from the amazing soundtrack to Lupin the 3rd, and Chisme has such smooth swaggering horns right out of a 70's jazz funk classic.
Jazz funk and metal is a match made in heaven, just not enough have realized it.
