Asked how it was different playing with Tornillo after performing with Dirkschneider during the band's early years, Herman told All That Shreds: "Mark is a really nice guy and really promising. It's kind of a different voice and Mark really doubles Udo in his personal way. I prefer the style of Udo's singing. He is original ACCEPT. There is this voice sticking in your head. On the new songs, which Mark sings for the first time in ACCEPT, it's a different character, but it's very good. You can't compare them, really. They are a match for certain things, but they are quite different people. I do like them both. I couldn't have the decision which one I would prefer. It would have been great if they would put a couple of albums with Udo and Mark together. That would be awesome."
