[He's] more than a colleague, more than a friend. I feel him like a brother. A man who loved every culture, you know, an open minded man. - Vasyl Slipak

Vasyl Slipak showed by his example an incredible will of Ukrainians to defend their native land. As a volunteer fighter, he demonstrated an example of patriotism and self-sacrifice to many, particularly our young people.(2018)

But that all changed in 2014, when Russia invaded the Ukraine. Slipak left the opera and joined as a volunteer with the free Ukrainian forces, fighting in the eastern Ukraine, carrying a belt-fed machine gun and adopting the nom de guerre "Meph" based on his highly praised renditions of the aria "Mephistopheles" from the opera "Faust." He adopted a traditional Ukrainian hairstyle, similar to a Mohawk, and served at various positions along the front lines in a maze of Russian minefields and trenches. Along the way, he became a folk hero to the Ukrainian people. It can truly be said that while the Soviet Union collapsed in 1991, and Ukraine became a separate country, its real independence dates from Maidan Square, and Wassyl Slipak is a national hero for giving up an incredible career and the luxury of celebrity and fame to help make that possible.

He was a brilliant singer and a brilliant person. Vasyl Slipak could never stay aside the injustice. When he decided to go to Ukraine, I tried to persuade him to remain in France, just willing to defend him from potential threat. But he insisted Ukraine needed him more than French opera.
