GasHead - Knuckles Avec Sombreros
Review: This is some of the best music I've ever heard. Megadeth meets Joe Satriani. Heavy tight riffs with melodic soloing. This band does all instrumentals, but these are not just instrumentals. They're songs! There's a beginning, a middle, and an end. Great stuff! I couln't get over how talented these three guys are. They sound like they've been playing together for years. The music has a great groove to it, and the soloing is not overdone. It's just enough to make the songs sound great. I can't say enough good things about these guys!

GasHead, Knuckles Avec Sombreros (Fist Music). Instrumental thrash with an understated Latin sensibility, GasHead's successor to LandSpeedRecord takes humorous liberties by tweaking metal's big, bad, bloated sense of itself. Instead of snarling goats and inverted crosses, the Fort Collins-based trio raises Molotov cocktails in a gleeful toast to abstract science, hockey and the absurd. Shred alert! -- La Briola

GasHead: Knuckles Avec Sombreros (Hapi Skratch Records)
By John La Briola
Despite the glaring lack of an evil, fire-snorting frontman, instrumental thrash trio GasHead avoids the kind of cliches that plague most aggressive-metal acts -- everything from overemphasizing Satan to celebrating global annihilation. Instead, the Fort Collins-based outfit injects its headbanging with humor and occasional Latin-flavored inflections. "Benediction," the album's opener, defies convention with an unlikely swing beat and a brooding narrator who toasts the album's guiding light (a hero named Atomic GasHead) with a round of Molotov cocktails. From that point onward, the boys shred in spades, showcasing six-string shootouts between lead and rhythm guitarists Mike Lopez and Derek Maness, while hide-beater Nate Scofield conducts a double-kick clinic. Polished production by local luminary Dave Beegle fleshes out a relentlessly heavy batch of tunes that hark back to the first wave of crunchy metallurgists Megadeth and Testament. Paying homage to Joe Satriani and Steve Vai (along with Avalanche defenseman Adam Foote, during "Into the Glass"), GasHead more than compensates for any absence of a bile-spewing leader. Stripped down to the basics, this stuff still packs a punch.

Review of Knuckles Avec Sombreros by Tamara McCollough
This Ft. Collins trio continues its ode to "instru-metal" nefariousness with it's second release, and manages to creep you out without saying a word. Despite the eye-rolling name, GasHead delivers tight, vehement tracks, featuring expeditious percussion by Nate Scofield and righteous riffs from tag-team guitarists Mike Lopez and Derek Maness. "Atomic GasHead" bears traditional hardcore elements, similar to Pantera and Megadeth, getting listeners pumped and pitiless. "Entangled....Spooky At a Distance" offers an exception to the instrumental theme with a guest vocalist --- Satan. Between the double-bashing drums and precise axe-shredding, GasHead drops what fans, bored with the current state of metal, have been craving for.

I'll be honest ˆ I had absolutely no idea what to expect when I put GasHead's "Knuckles Avec Sombreros" into the CD player. The artwork suggested something less than heavy metal or hard rock for that matter ˆ it evoked an image more fitting for Los Lonely Boys, assuming they were modern rockers rather than Tex-Mex kings. The title was just flat out confusing - "Knuckles Avec Sombreros"? English, French, and Spanish are all represented in the album title with nary a link among them.So what's "Knuckles Avec Sombreros" all about? Well, it's about living in the moment with shredding being the order of the day. Co-lead guitarists Mike Lopez and Derek Maness shred their way into six-string bliss on every track. While not entirely over-the-top, it's pretty clear to me that restraint wasn't necessarily the first thing these cohorts in guitar mayhem concerned themselves with upon waking up each day. Nine original songs are augmented by two particularly impressive cover songs. The originals are up-tempo rockers that are uplifting and expressive without being too weighty for their own sake. The covers include a balls-out expanded heavy duty version of George Lynch's guitar solo track "Without Warning" while a fairly faithful rendition of Def Leppard's instrumental classic "Switch 625" gets an honest treatment from the band. Technical proficiency doesn't get in the way of having fun with these guys. GasHead show a strong sense of humor (despite a lack of lyrics/vocals except for the intro track) and playfulness missing from most artists' outward musical expressions. There is a lot of joy expressed on "Knuckles Avec Sombreros" and it's nice to hear for a change.I thoroughly enjoyed "Knuckles Avec Sombreros" and if you are the slightest bit interested in guitar instrumentals that GasHead are worth checking out.
