Blizzard of Ozz is a heavy metal album by Ozzy Osbourne, recorded in Surrey, UK and released on September 20, 1980 in the UK and on March 27, 1981 in the U.S..
This is Osbourne's first solo album and one of the two studio albums he recorded before guitarist Randy Rhoads' death in March 1982. The tracks "Crazy Train" and "Mr. Crowley" were released as singles. The former peaked at #9 on Billboard's Top Tracks chart and has remained a staple of pop, hard-rock, and classic-rock radio for more than 25 years; it remains Osbourne's most recognizable song.
Blizzard of Ozz remains Osbourne's highest-selling album to date, selling over 4 million copies in the U.S. alone.
