The artist is a female, i heard this song maybe in 07 or 08? i heard it on youtube on a amv called hollow ichigo.
the song starts of very very low and begins with the sound of i think an elephant? not to sure. but i correctly remember a trumpet that blows its sound twice and then he drums pick up louder and louder til a female begins to sing but it sound like opera and rock? and its either 5 or 6 mins long?
