Helena Ros Redon and Marta Torrella i Martínez are Tarta Relena. Together they explore the rich vocal traditions of the Mediterranean, singing in languages such as Classical Greek, Italian, Spanish, Latin, Catalan, Ladino, and more.

Their music blends sacred and secular influences, drawing inspiration from flamenco, lyrical song, traditional music, and electronic experimentation. Influenced by Mediterranean folk, Georgian laments, and the mystic works of 12th-century visionary Hildegard von Bingen, Tarta Relena crafts a vibrant sonic world where the past and future converge.
