Drawing on Celtic folk influences but also a bewildering welter of other traditions — the Balkans, South Asia, Basque Europe, Native America both North and South, etc. — Peia herself is a stylistic puzzle but her music offers a powerfully engaging listening experience. Her third album veers from the rollicking puirt a beul of “Ciamar A Ni M’in Dannsa Direach” to the atmospheric Andean folk of “Que Me Medicina” and “Txoria Txori,” with stops along the way for original songs. There’s a lot of eco-mysticism in here, and if that makes you roll your eyes, I get it. But try not to let it keep you from enjoying Peia’s astounding voice and her admirably adventurous approach to arranging.
