siLLy puPPy ZU is an atypical power trio emerging from Rome, Italy in the 90s delivering some energetic and unconventional hybrid music. I was totally unfamiliar with this group before their 11th studio album CARBONIFEROUS and I have not heard any other albums before this but from what I have read they have taken on a more heavy and distorted take on their RIO / Avant-prog meets math rock music. There are a several groups this band reminds me of. They have a musical delivery approach like the avant-jazz French group Jean Louis but the heaviness and chord changes have a Fantômas feel as well which is particularly true on the two vocals tracks that have Mike Patton making a cameo appearance. This could be due to the fact they toured with Fantômas and Melvins in 2006. ZU also has a groove on some tracks similar to another strange band called Chrome Hoof. This is especially noticeable on the first track “Ostia.”

Any way you slice it ZU is an RIO band in structure with an avant-jazz-metal veneer consisting of the unconventional trio of instruments that includes bass, drums and baritone saxophone. We do get a couple guest guitarists lending a hand on “Chthonian” and “Obsidian” but Massimo Pupillo's extremely heavy fuzzy bass pretty much delivers as much distortion as the music can handle and Luca Mai's sax playing takes the place of the traditional guitar. He handles rhythmic duties for the most part but also contributes some sizzling solos that bring John Zorn to mind. Jacopo Battaglia has a jazz drummer's method of dancing around the strange chord progressions and contributes more of a complementary sound than an expected backbone of the band. The musicians spend their time weaving around each other in a way that makes it hard to focus on any one particular instrument that stands out but there are times when solos are thrown in.

This music is highly addictive. It was love at first listen for me but it only got better the more I listened to it. The band makes full use of tones and distortion as a key part of the musical structure and the musicianship is top-notch. By blending various aspects of math rock, noise rock, punk, jazz, grindcore and a touch of repetitive drone doom at times, they have created a very intricate and disciplined style of music that doesn't come off as being as complex as it is. A true treasure tucked away under the various categories of RIO, avant-prog, avant-garde metal, or free jazz, but nomenclature aside it is simply a unique sound that fans of adventurous, energetic and unorthodox fusion will find most satisfying.
