Metal Health was the breakthrough album for the American heavy metal band Quiet Riot and their first record without deceased legendary guitarist Randy Rhoads. It was released on March 11, 1983, bolstered by the #5 hit "Cum on Feel the Noize" and the #31 hit "Metal Health". Metal Health was the first heavy metal album to hit #1 on the Billboard Music Charts pop albums chart. It knocked The Police's Synchronicity out of #1 in the U.S. The album went on to sell more than 6 million copies and is considered a classic among heavy metal fans to this day. However, some critics such as the All Music Guide , perceive it as a one-hit wonder, owing to Quiet Riot's relative lack of critical and commercial success with following albums (and subsequent disintegration) towards the end of the 1980s.
