Opla is a duo consisting of Hubert Zemler (Zebry a Mit, Zemiter, Melatony and LAM, among many others) on percussion and Piotr Bukowski (Javva, Xenony, Tutaj) on guitar. Together they interpret the most ancient obereks - traditional Polish dances - focusing on their trance-inducing qualities. Their debut album Obertasy was released earlier this year on Ersatz, an Instant Classic sublabel.
