Since Oliver still plays concerts "oberkörper frei", it is not that difficult to find photos of his back. Oliver has a lean and muscular body, and even though he is now in his 50s, he is in great shape.
While he painted his body dark for the entire 2023 Europe Stadium Tour, if anything, darker complexions can make muscles pop in bright light. My pick for this challenge is a photo from Budapest by Matthias Matthies. The contrast colours in the photo make it really stunning.
Bonus material:
1) Another photo from 2023 Europe Stadium Tour, this time from Brussels taken by Jens Koch. I love when Oliver and Richard find together on stage, and this photo from Mein Teil is such a great example of that.
2-3) Screenshots from the Making of Rosenrot. The band members didn't want to use make-up for the flagellation, instead they drank vodka and went out in the cold and whipped themselves.
4) I love the atmosphere in this photo by Frédéric Batier, from Völkerball, where Oliver takes a moment for himself in Budapest 2005.
5) Oliver getting his in-ears taped to his back, by Jens Koch 2019.
6) Screenshot from one of Jens Koch's videos 2023.
7) Silly little promo video for the Mein Land music video, where we see Oliver and the girls. It does show his back though.
8) Oliver during the shooting of the Mein Land music video, from the photo book by Frédéric Batier.
9) I guess these last two photos are what people expected. First out, Andreas Mühe's photo of Oliver, naked, in Winnipeg 2012...
10) ...and finally, Missy Funnybunny's photo of Oliver, taken in Paris 2012. This is probably the most well-known photo of Oliver's back, and deservedly so. It is really good.
