1994's Monster found R.E.M. making a stylistic shift on their ninth album. Filled with heavily distorted guitars and dense, sonic textures, Monster focused on identity, on the concept of celebrity and on the notion of reality. The critically acclaimed album was also a huge success with fans-it was certified as 4x platinum in 1995, and went to #1 in the US, Canada and the UK, among other territories. Features hit single "What's the Frequency, Kenneth?"
