Australian twin sisters, Nervo, have suspiciously joined in the Beyonce remixes with their remix of "Grown Woman." Rumor has it that these mega DJ's have something to do with Beyonce's album campaign, at least according to Idolator.
Nervo's remix of "Grown Woman" starts strong with house pumping beats fading into something more like a trance halfway through, returning to the screaming synths, house beat, and calypso drums heard in the beginning.
