The Orlando/Sweden/Puerto Rico-based Eco Discos label has -- with a handful of CDR releases -- been quietly establishing itself as a boutique for contemporary, experimental ambience. With "Disonancias," the debut from Eco vice president and Orlando resident Raphael Irisarri, the label is moving into the realm of small-press, silver-disc releases. Limited to only 1,000 discs and immaculately packaged with artwork by Thomas Ekelund, it's an impressive introduction to the label. Irisarri collaborated with other Eco artists including Jorge Castro and Daniel Wictorson to create the synthetic dreamland of "Disonancias," and the sound is firmly aligned with instrumental post-rock (and bears scant resemblance to Pierre Henry's "musique concrete"). Sweeping sheets of processed guitars and wandering feedback tones are reminiscent of Robin Guthrie's more halcyon moments, while the overall effect is how "Discreet Music" would have sounded if Eno had bothered with melody. It's encouraging to find bold artists like MCE and labels like Eco in your neighborhood; it's even better when they're good at what they do.
