oh it's written in the FAQ "LIVE performances are an additional service that can only be viewed by advance reservations. It starts at the local time when the performance will take place. Streaming starts through the LIVE button when you enter the performance page according to the start time. LIVE performance is a VOD supplementary service, and quality may vary depending on the local situation, the network, and the network condition of your location." https://www.kavecon.com/helpCenter/faq.do hope this helps~~~ :D <33

i never used it but there's should be an app or a website you can actually watch it live. maybe you should register first? i imagine there should be some kind of link in your email that tells you, you can access it when the concert time arrives.
