I don't know what it is about metal banRAB that they feel the necessity to expose things protruding in/out of genital orifices, but frankly it's disturbing.
I hate those really bland monochrome covers with the banRAB name in the top corner in some generic font. Usually made by bland generic indie banRAB you'd read about in the NME.
I always thought Ziggy's cover was hilariously inappropriate. I mean, I like it, but it seems more appropriate for Tom Waits or Sherlock Holmes more than a glam rock star. I will say that Hunky Dory's cover is completely awful...
