Interesting Advertising

Over the past few days I've seen some interesting/different advertising methods used by bands.
Bands including Slipknot & Trivium had banners being flown by planes above Reading festival (and Leeds I'd assume) with details of their tours (there were other bands too that I can't remember) and numbers to call to get tickets.
Fall Out Boy have released a free EP for download that features several artists signed to FBR Records which had a link sent to every person signed up to all of the artists' mailing lists.
A local Catalan band used the bull burning in the town to advertise themselves, they painted the bulls with information (singles, albums, band name etc.) before they were set loose to run through the streets where about 2,000 people would get to see them. (Totally agianst the priciple of the event but interesting way of advertising).

When I see more I'll add them =]
