Midnight Oil - I know they're a bit of a cliche. I enjoy spunk punk sometimes.
If you like Midnight oil, you'll love early Wire, The Flesh Eaters, Gang of Four, Bush Tetras, Pylon, and The Stranglers, as well, provided you haven't heard of them or already have them in your collection.
Also, if you like modern Garage Psych, and Psychadelic, you'll want to listen to
this every Saturday at 4pm EST to get a good dose of it.
