I haven't heard about that, outside of hash tagging (is there a specific tag for his concerts?) what's the best way to show him?
If it's a standing room only concert it's on you if you want to move around. I got different shots from various povs because once people started going HAM it wasn't really ideal to be trying to shoot while everybody around you is jumping and pushing people.
Get your shots while you're close to the stage if you plan on moving, because chances are you're not going to get back to where you were once you leave.
the BEST way imo would be to find someone who works at the venue and see if they can get in touch with his manager directly while he's there

swap emails and then send him the shyt directly, that way they'd know who you are and you never know, venue might start giving you press passes or the manager might hit you up directly for more shyt
and unless im purposely trying to get the crowd in my shot im gonna ask the people at the venue if they have a photographer pit BEFORE i attempt to move through some drunk nikkas cuz the first time someone's elbow hits me the wrong way im swingin
the reason i'd do my shyt more directly like that is because i feel like a LOT of people dont do that, they just put it up on the internet and hope the artist stumbles upon them, someone else would prolly just steal your shyt and try to take credit, or the artist would see it randomly and not know who the hell took it or how to contact you
