Metal Female Voices Fest was a heavy metal music festival dedicated to female vocalists, held annually in the Oktoberhallen in Wieze, Belgium since 2003. It was organized by the Metal Organisation, which later changed into "2 Wild 4 agency". The festival enables smaller and unknown bands within the female fronted genre to perform on a big stage beside bigger and more famous bands. Over the years, they gave away special awards or organized a warm-up which allowed bands to compete to perform on the festival for the next year.
