I tried this openers with a HB7

(I noticed her earplugs)
Kowalsky: (with a smile)Oh my god!! What's your excuse for the earplugs in a concert?
HB7: Because the music here is so loud, I don't wanna become deaf (whit a smile)
Kowalsky: (I started to move my mouth like to say something, but without emit sounds)
HB7: hahaha
Kowalsky: Have you ever seen before?
HB7: No, this is my first time, I saw them only on Youtube
Kowalsky: Ok, why don't we go forward to see them better?
HB7: ok! let's go

After the concert we talked about music and ohter band for a while, then I said

kowalsky:" I gotta go now. You know? you are very sparkling, give me your number for hang out sometimes.
HB7: ok and thanks for the company

I was afraid to try a kiss-closer and now I think it was a mistake.. next time!!!
