There is a concert festival in Austria, Nova Rock.
They have a new service this year - 30 mins after the concert you can get the gig on an USB stick for 17 Euros. Extremely cool, in my opinion. I know they did it with CDs after the concerts already, somehow I even like the idea with the USB stick more. Pity the Stones can't do that...it should be included in the ticket price!
