Travelling around Australia once more in early 2012, the Soundwave Festival boasts one of the biggest and heaviest line ups in the world. This year the festival features a lot of popular acts from the nu-metal wave of the 1990's - including headliners System Of A Down, Slipknot and Marilyn Manson - as well as bands currently dominating the metal and post-hardcore scenes. This playlist features most of the artists from the 2012 line up.
