Roots of Randy Rhoads

Mountain was an American rock band formed on Long Island, New York, in 1969. Originally consisting of vocalist-guitarist Leslie West, bassist-vocalist Felix Pappalardi, keyboardist Steve Knight, and drummer N. D. Smart, the group disbanded in 1972, but reunited on several occasions prior to West's death in 2020. They are best known for their 1970 smash hit song "Mississippi Queen", which remains a staple of classic rock radio, as well as the heavily sampled song "Long Red", and their performance at Woodstock Festival in 1969. Mountain is one of many bands commonly credited with influencing the development of heavy metal music during the 1970s. The group's musical style primarily consisted of hard rock, blues rock, and heavy metal.

John Michael "Ozzy" Osbourne was an English singer, songwriter, and media personality. Dubbed the "Prince of Darkness", he is widely credited as a pioneer of heavy metal music. He co-founded the band Black Sabbath in 1968, and rose to prominence in the 1970s as their lead vocalist. He performed on the band's first eight studio albums, including Black Sabbath, Paranoid and Master of Reality (1971), before he was fired in 1979 due to his problems with alcohol and other drugs.
