In the clip the France's Got Talent contestant walks out in front of the panel of judges before letting rip on the unsuspecting judges with her harsh guttural death metal vocals.

The 24-year-old educational assistant, Rachel, appeared on the show will full hair and makeup, in an unassuming black dress. She than began screaming in to the mic to double bass drums and distorted guitars.

While the judges didn't agree with her choice in music, they were impressed with her ability.

The first judge isn't open-minded enough to accepted her left-field style and presses his cross button early in the song.

Meanwhile the other judges commended her for her unusual style and ask her how long she can sing like that for. She says “one hour,”  they look impressed and put her through to the next round.
