LA-based pianist Kate Simko and Chilean electronic-head Andres Bucci recently began collaborating as Detalles. Their debut album is a supple, minimalist tapestry of precision click-pop and plaintive piano and other acoustic instruments with a South American flair. “Rhodes Relejadas” has all the quietude required of most experimental electronic music, but Detalles mute the effects to produce a warmly wonderful cut. On the other hand, “Plus/Mas” brims with Akufen-ish uptempo pluck without succumbing to crass techno tendencies (likely due to John Tejada’s mastering). Delightful in its execution, Shapes lilts through themes in ways usually limited to classical compositions.
