In a concert of over two hours, the greats of American alternative rock promoted their latest album, "Around the Sun", as well as numerous old hits.
The audience shouted "Stipe! Stipe!" to lead singer Michael Stipe, who jokingly responded that his family came from Germany but might have Croatian roots.
Chris Eckman of The Walkabouts and Croatian rock group Bambi Molesters' guitarist Dalibor Pavicic joined R.E.M. on stage for an encore.
