This group is an Italian prog band. That is significant because Italian prog is a sub-genre all its own. There is a type of vocal, nearly operatic in some ways, that is a big part of that type of music. This only shows bits of that. What this has is a lot of great music. It's often hard rocking. There is a healthy helping of jazz and fusion built into it. It's powerful music, even if (like me) you don't understand the lyrics.
