Anyone else getting strong Steven Wilson/PT vibes from the beginning of Towards The Blue Horizon? That falsetto Mariusz does sounds very Steven Wilson-y to me, and reminds me a lot about what I used to love so much with the classic PT albums.
As much as I like progressive Riverside (ADHD is probably my favorite album of theirs, followed by SLS), they do progressive songs really well, but I think this is the kind of album where Mariusz really shines as a vocalist. He has that really nice and peaceful delivery and his voice is really great for the "softer" moments. There's still some heavy moments, but it's more Progressive Rock heavy and less Progressive Metal heavy. (if that makes any sense)
This definitely feels like the most mature album they have done, and you can tell they're more confident in themselves now. SONGS was still a good album, but it felt a bit like playing it safe in some areas, whereas this one, they take the leap of faith and it pays off.
