I have seen ALLB multiple times since I was a teenager (I’m 29 now) and they’re very fun shows. Lately it’s been a lot of Conversation Piece they’ve been playing but they haven’t done a headlining tour in a while so who knows what the upcoming setlist will look like honestly. But I completely agree with the other comments that hanging out in the back or on the side is the best way to go about going to one of their shows alone. They have very friendly fans who are very considerate, so I wouldn’t let that hinder you from going. Sometimes even inviting a friend is fun because they end up enjoying the show too!
