Query: One of the great prog metal bands

This is a great release from a underappreciated band from the 80s. They reached a high point in the 90s with this one and other albums like Phobos. It's great to hear that they are continuing as a band despite the tragic death of their mastermind guitarist. It is great news that they will have a new album early next year. Let's hope it's as strong as this effort.
