As I said in another post, Otep Shamaya is like a female version of JD. She is one of the best female vocalists I have heard! Her songs are heavy, catchy and often controversial. She alternates between heavy growls and screams, to sweet melodic singing, to spoken word. She is an artist in every sense, her lyrics are very poetic and filled with representative imagery.
If you haven't checked out her music yet - DO ITTTT!!!! Now! Go go go go go!!
