How do I get with a guy from a band?

Seeing a small band (1000 followers on Instagram) tomorrow again for the second time. I saw them last month too

I have a crush on one of the band members. I was front row and my friend told me all the band guys kept looking at me so that gives me hope but it may also be because of the way I was dressed. People tell me I could have anyone I want but it doesn't feel that way, I'm very shy too and I can't talk to people even when I'm drunk

I really want to talk to this guy from the band though this time. We accidentally locked eyes a lot last time as well. I'm 20 and he's like 15 years older than me at least too. Help? Like what could I say to start a conversation for example
