Exelent wie immer .....und mit Ina im background mega 🤩🤩🤩

Keep up the good work. Oliver has an awesome sound and quality to his voice, I still listen to the At Vance albums with him. I'd love to see him get the credit he deservers, he is one of the best voices and creative forces in the Rock/Prog Metal genres in the past 20 years.

Excellent as always, greetings from Argentina Oliver
