On their 2006 self-titled album, Rodrigo y Gabriela offer up a fierce set of acoustic instrumentals that garnered the Mexican guitar duo international attention. Technically accomplished, playful, and emotive, these tracks work in the flamenco and folk vernaculars while reverberating with rock energy, as revealed on the fleet-fingered "Tamacun" and the highly percussive "Diablo Rojo." However, the real showstoppers on RODRIGO Y GABRIELA are the pair's excellent covers of Metallica's "Orion" and Led Zeppelin's "Stairway to Heaven," which both honor the hard-rock originals, and resonate with impressive added flourishes.
