Mal Blum is all ages. For future reference, age restrictions are usually noted on event page. The venue is appropriate for all ages shows.
I think he should be fine, it just depends if the event is 21+ or not. Check if there is a facebook page for it and confirm if he's even going to be allowed in.
they do check ID since they have a bar, but if you're underage they just put X's on your hands.
Coop atmosphere for your 16 year old. Seems most events are age appropriate.
