I've always loved Heavy Metal Music, maybe because it was developed around the time I was born, the late 60s and early 70s. 
I enjoy it too.  The bands Black Sabbath and Led Zepplin led to the genre's popularity in the 70s
Ah! I like them, And Deep Purple as well. 
I prefer the trash metal that was big in the 1980s.  Bands like Metallica and Slayer really added something to the music scene when they came out
Ah, yes. Metallica. My husband saw them in person before they became big. Didn't realize the band was formed back in 1981. 
Yes, they were formed by James Hetfield and Lars Ulrich.
And from what I understand, they are from Los Angeles, CA.
