Commented NIGHTWISH keyboard player and main songwriter Tuomas Holopainen: "This must be the sixth or seventh time we’re working with these people. We’ve realized what they can do during these years. So it’s really not a surprise anymore but it hasn’t ceased to amaze me. The level of professionalism is just unbelievable. But even more importantly, they clearly like what they’re doing. The guys we’ve worked with for over 10 years are still up for it."
Added session-drummer Kai Hahto: "The professionalism is amazing. We were recording ethnic percussion yesterday. Some of the guys had played on Star Wars movies – and done Hans Zimmer soundtracks. I thought of myself as a humppa drummer. It was pretty amazing. They know their prima vista. You give them the notation, and they’ll nail it in no time."
