This is a classic in every sense of the word. Sleep was one of those bands that had a heavy influence on most of todays fuzzed out stoner rock. Matt Pike has went on to form High on Fire which are good to but in my opinion Sleep was better. Holy mountain has a wicked sound, and it’s slow as hell. They have huge build ups until they drag in a riff that will melt your speakers.The Orange amps they used give this release a distinct sound. This album is worth every penny.
