House of Blues- signs allowed?

I’m taking my daughter to see Madilyn Mei in the Bronze Peacock room tonight- think mostly preteen fan girls. This is her first concert, and we’d like to bring a sign. Anyone know if this is allowed? I’m not getting my calls to even connect to the number they have listed.

ETA: Answer received! We’ve settled on a tiny, unobtrusive sign for one of her favorite lyrics so that it’s quick and doesn’t ruin everyone’s view! Thanks yall! 🙂
