Problem for me is most gigs I go to are even heavier than Metallica so most people really won't like it.
Gojira the last gig and Lorna Shore the next and I don't know anyone who likes them lmao.
I don't really know anyone who likes the same kind of music as me so end up going to a lot of shows by myself and it's great fun.
Granted I like spending the entire show in a mosh pit so it's not as much of a group activity anyway.
