Georgina Lobonț will appear at Cluj Arena on 4th Only 3 percent of tickets are left. Tickets range from 690 lei to 1384 lei. Sometimes you might find them on sale for 582 lei. (But with only 3 percent left, you might be lucky to get a ticket at all.)
The ticketing system is pretty cool. Unlike those in film festivals and sporting events, when you buy tickets for the Lobonț concert, they are automatically placed together. You can try it at the concerts50/stubhub website. But I guess you might have a little less control over where you sit.
Here is a video from a previous concert.
