Monotract has been experimenting with noise rock since the late '90s. The trio's latest, Trueno Oscuro (Spanish for "dark thunder"), finds guitar, drums, bass, and tweaked electronics sputtering through 29 minutes of sloppy racket.
Instead of producing a finished product, Monotract seemingly documents itself knee-deep in the artistic process. Trueno Oscuro's peak comes early -- the first nine minutes, in fact. On the opener, "Muddy Thunder," the band belts out warbling guitars, eventually stuttering into a synthed-out, new-wave haze. But Monotract quickly explodes into a shoegaze supernova before quieting down and reveling in the ghostly tones of "Under My Arm," a curious track wherein bassist Nancy Garcia fucks around with some Eraserhead-like vocals.
Outside of "Big N," where the final seconds dive into a black hole of scorching noise, the five remaining tracks are interesting, but don't introduce anything new -- just bloated re-arrangements of the disc's first two cuts.
Although Trueno Oscuro is worth a half-hour of time for serious fans of noise rock, the disc would make a greater impact if Monotract exercised some editing.
