Query: BRUTAL DEATH / THRASH AT ITS FINEST

THIS IS ONE OF THE HEAVIEST RECORDINGS EVER. IF YOU DIG DEATH METAL OR THRASH METAL,THIS WILL GRAB YOU BY THE BALLS. EXCELLENT VOCALS,GUITARS AND DRUMMING. ROB BARRETT IS ONE OF THE GREATEST GUITARIST AND IT SHOWS. HIS VOCALS ARE JUST AS GOOD. HE IS A GIFTED MUSICIAN. A RECORDING GUARANTEED TO SMASH SKULLS. THE MAN HIMSELF JAMES MURPHY ADDS HIS GREATNESS HERE TOO.
