Contrary to the implication of its title, Guitar Nova hardly sits within the nouveau flamenco niche. The unique, rhythmically charged music of Norwegian guitarist Erik Wøllo is as pristine as airborne crystals, using a cornucopia of strings from fretless, slide, and 12- and 6-string guitars to acoustic bass, balalaika, and kora harp. Wøllo's technique covers a wide range of voices, too, from pinprick twanging to deep thumping, with many of the passages electronically altered and overdubbed; his careful picking lets every note have its own life and impact. The album begins simply enough, with a lovely melody on "Summer Tomorrow" that could have been penned by that other great Erik -- Satie. The lively "Road" mimics the rolling patter of tires chewing up the pavement; while the bass hums like the satisfying sound of a well-tuned engine. "Source" begins with a buildup of mournful wails; the layers of melody are then swept up into an ever-growing rhythm machine driven by pulsing bass pistons. "Hildring" is a delirious round that spins off rhythmic cycles like fractal patterns. Abounding with good-humored spirit yet sophisticated enough to be a challenge, Guitar Nova stands up after many listens.
