The greatest irony is that I hate their music almost as much as I am enthralled by it. Acid rock was never supposed to be bright and inspirational, and indeed if you really crave a peppy song then you should rather buy yourself a pop album. The music of Pink Floyd is perfect for the mood that it set out to create. There is no feeling of insecurity, loss and helplessness that their songs do not probe and bring to the surface.
Every random sound on their songs is actually a road marker to that eventual goal of making you feel as miserable as possible. They lack the seething anger that other bands display when faced with a intolerable situation. Their cold acceptance of the hard realities of life and the death of dreams are both horrifying and strangely soothing at the same time. They are one band I'd avoid like the plague, were I really depressed! Floyd are the undisputed kings over their self constructed empire of sadness.
