I was thinking of creating an anonymous ticketmaster account using public wifi since they block VPNs and just have them email me updates, but they required a phone number for the sign up so I scrapped that idea.
Edit: I decided to sign up for songkick as someone else here mentioned. It seems pretty polished and its entire purpose is concert discovery. It never asked for any unnecessary extra information either such as first and last name and phone number, just an email and a password and boom.
This but I just gave them my email to let me know when bands I like are in my area. Super easy to use and very reliable. Even has tiny shows in community centers listed for me
