This completes the trinity of unholy Old School Metal bands.

4 Dio Dio was an American heavy metal band formed in 1982 and led by vocalist Ronnie James Dio, after he left Black Sabbath with intentions to form a new band with fellow former Black Sabbath member, drummer Vinny Appice.

Holy Diver, The Last In Line, Dream Evil and Sacred Heart are some of Dio best works.

5 Ozzy

I wanted to put Dio over Ozzy but I just couldn’t.

6 Rainbow Rainbow are a British rock band led by guitarist Ritchie Blackmore from 1975 to 1984 and 1993 to 1997. They were originally established with Ronnie James Dio as the lead singer and lyricist. Rainbow were ranked No. 90 on VH1's 100 Greatest Artists of Hard Rock. The band has sold over 28 million albums worldwide. The band's early work primarily featured mystical lyrics with a neoclassical metal style.

Great until post Dio.

7 Motorhead Motörhead were an English heavy metal band formed in June 1975 by bassist, singer, and songwriter Ian Fraser "Lemmy" Kilmister, who was the sole constant member; guitarist and songwriter Larry Wallis; and drummer Lucas Fox. The band's harsh vocals and fast paced tempos helped inspire speed metal and thrash metal.

Lemmys vocals aren’t my thing but out of respect I put them on this list.

8 Alice Cooper Alice Cooper was an American rock band formed in Phoenix, Arizona in 1964. The band consisted of lead singer Vince Furnier, Glen Buxton, Michael Bruce, Dennis Dunaway, and Neal Smith.
9 Accept Accept is a German heavy metal band from the town of Solingen, originally assembled by former vocalist Udo Dirkschneider, guitarist Wolf Hoffmann and bassist Peter Baltes.

I just assumed they were Thrash Metal until I listen to them.

10 Diamond Head Diamond Head are an English heavy metal band formed in 1976 in Stourbridge, England. The band is recognised as one of the leading members of the new wave of British heavy metal and is acknowledged by thrash metal bands such as Metallica and Megadeth as an important early influence.
