(SOUTH ASIAN ELECTRONICA) In his essay "The Plural Dance Cultures of New York's South Asian Diaspora," Professor Ashley Dawson writes that Manhattan-based DJ Rekha "explicitly designs her [mixes of South Asian dance music] in a manner that works against the forms of chauvinism that characterize spectacles of ethnic heritage such as the Diwali festival. Her mixes are clearly intended as a corrective to the chauvinist, heterosexist cultural nationalism that prevails in certain segments of the [Indian] community." Trust me, DJ Rekha is the real deal.
