Euphoria indeed. Rie Lambdoll and Mayuko are the two euphoric Synth Sisters, Osaka-based musicians who also comprise Crossbred. “Euphoria” is the duo’s long-awaited second release, following their 2014 debut. This release consists entirely of new Synth Sister recordings, featuring Mayuko’s synthesizers, and Rie’s electric piano and synthesizers as well as her celestial vocals. The euphoria on offer here features equal parts of angelic arpeggios, seraphic sequences, meditative melodies and transcendental timbres, masterfully mixed and mastered by Kabamix. The pieces here, all composed and produced by Rie Lambdoll, combine drifting drones with rhythmic elements sure to appeal to fans of Tangerine Dream; (Terry) Riley-esque meditations melding with psychedelic musings in blissful ease.
