group The Mars Volta and R&B singer Brandy. Of Brandy, Frusciante says "she's doing something different, she's doing so many vocals that there is never a space. Whenever one voice stops, another one does something in its place. There's very little space, and there are so many vocal parts that are breathy, you don't know what you're listening to. There is so much going on, you can't hear her voice with your conscience, you have to hear it with your subconscience.
