Going to a concert Alone

Do you have any experience about it ?

I was thinking about going to a shoegaze/grunge show close to me but none of my friends are into these genres so i'm left all on my own. The thought of going alone scares me, mainly beacause i'm not used to going music shows in the first place but also bc i fell id be like a fish out of water.

Do you have any suggestions about this ? what could/should i do ?
