Valerie Teicher (born Buenos Aires, Argentina), best known by her stage name Tei Shi, is an Argentine singer-songwriter and producer currently based in Brooklyn. Her music is so wonderful, ethereal, similar to the Cocteau Twins. Her videos are so other-worldly, matching perfectly her music. Listen to her on a late night, just when you need to relax. Her beautiful, gentle voice just brings wonderful dreams. I love her. She is beautiful, inside and out.
