Home grown rock. Go the SCREAMING JETS, AC/DC, Midnight Oil, Powderfinger, Frenzal Rhomb, the John Butler Trio, etc.... Also some overseas acts like the Red Hot Chilli Peppers, Foo Fighters, The Jam, Guttermouth, etc.. and yeah i'm pretty anal about my rock, no Celine Dion or ENIMEM want-to-be's in my collection!
