Ooh, I've listened to them since I was little, too, Ash. My oldest brother has been a fan for years, and some of my earliest memories include standing on his bed, headbanging to Enter Sandman.
So I've grown up around them & their music, and as an early birthday present, my parents got me a ticket to see them last Saturday with said brother. Glyder (Irish band), Mastodon, Alice in Chains & Avenged Sevenfold were supporting, so it was a bit like a mini festival, we were there all day. It started getting dark just as Metallica were coming on, so the pyrotechnics looked great, and then the music. Eee, the music<333
The older songs were the highlight of the night tbh. I don't know a whole lot of their music, just certain songs, mainly older ones. It was still awesome though. xD
