Ticketmaster and Live Nation have destroyed the concert experience. But it didn’t use to be this way. Today, Oasis and Taylor Swift tickets might go for thousands of dollars, but back in 1955, you could see Elvis Presley in concert for less than the modern-day equivalent of $20.
Here in Greece concert performances of foreign bands/artists cost around 30€ to 90€ (depending on how well known the artists are) and many times it is a festival with more than one band performing.
I think Greek bands/artists charge around 0€ to 30€ for concerts (0€ because some do it out of charity, to help a cause)
Btw I think I’ve never used ticketmaster, we have a viva.com which handles many of the tickets (and it too is an annoying service).
