Quiet Riot - Metal Health

Metal Health was the first heavy metal album to reach number one on the Billboard 200 chart, replacing the Police's Synchronicity at number one in November 1983. Due to its commercial success, Metal Health is regarded by some as the catalyst that opened the door for hair metal's immense popularity throughout the next several years. The album went on to sell more than ten million copies worldwide and over six million in the U.S. alone, being certified six-times platinum by the RIAA.
