scusa widehole ma qui si dice la propria.
sorry widehole but it's just a matter of opinion. if someone preferred tool's performance to NIN's you shouldn't offend him for his tastes. And you speak of openmindness and freedom...
However I didn't see NIN, I had to get back home but I'm sure it was a very good performance; I can only say that Tool's show was how a rock concert should always be, they brought me away last night.
