15. 'Alex Descends Into Hell for a Bottle of Milk'
U2 were pretty much off the grid in 1990, though Bono and the Edge did emerge to write the score for the Royal Shakespeare Company's production of A Clockwork Orange. The Edge was listening to a lot of industrial music at the time, and their song "Alex Descends Into Hell for a Bottle of Milk" was the first glimpse U2 fans got of the new direction U2 were headed in the 1990s. It's also the complete opposite of the American roots sound of Rattle and Hum. The instrumental came out in 1991 as a B-side to "The Fly."
