Yellow Sisters

Yellow Sisters is a Czech female vocal quartet, known for singing a cappella. Its members are Antonia Tereza Nyass, Barbora Vaculíková, Lucie Hawa Goldin and Léňa Yellow – Lenka Jankovská. Their singing is inspired by many musical styles and regions (from African traditional to American gospel, reggae, jazz or funk). They call themselves "sound illusionists" and their repertoire is purely self-composed.
Their sound is quite experimental and playful, based on the rhythms of the Czech language.
They are known for their strong support for human rights.
They have been performing since 2005 – their first demo CD was produced in that year.
