Master of Reality is the third album by the hard rock band Black Sabbath.It was released in 1971. Master of Reality starts off with guitarist Tony Iommi taking a very large bong hit of marijuana and coughing in the song Sweet Leaf. The next song is a pro-christian song, which surprises many people, called After Forever. The album features 2 short opening peices to 2 of their songs, which the band seperated from the actual tracks to make the album look like it had more songs, which they did many times. This album is number 298 on Rolling Stone Magazine's list of the top 500 greatest albums of all time.
