It is always better to review the concert information. It may be that tickets run out or that they do not sell it in person on the day of the concert. When I went to see a group there I saw no place to buy tickets, only where they checked that the tickets were current to let people enter.
If it is better always check online about the concert. I still went to Mana's concert. And I didn't see ticket sales. Only of articles of the mentioned group. Check out that you are safer ... Good luck
