Black Sabbath was undoubtly the originator of Heavy Metal and their music is the source of metal riff that fuels up the modern metal bands of our times. I like the way they play pure metal and I love Black Sabbath as they are the first Heavy Metal band that ever existed. They are one of my greatest influences in playing and making my metal music until this time. I wan to share the song that influences the movie "IronMan". I hope you like it.
