Sonata Arctica is typical speedy Finnish power metal, with lots of catchy guitar riffs and wailing keyboards throughout. I'm a pretty big fan, and I'm really hoping to see them on the bill at PP next year. In my opinion, each of their albums has strenghts and weaknesses. Ecliptica, the first one, is very intense and ridiculously fast, which makes it a blast to listen to. But after repeated listenings, a lot of the songs on the album start to run together. Silence has a handful of really outstanding, catchy songs like "Weballergy", "San Sebastian Revisited", and "Wolf & Raven", along with a few other solid ones. But there's also a number of slower songs that are a bit bland. Winterheart Guild, the most recent one, is fairly slow overall, but I think the slower songs are a lot more interesting than the ones on Silence. More intricately layered harmonies, and lots of great vocal moments throughout. I don't listen to Successor very much, because half of it is live, and it sounds pretty poor. They also do a completely kickass rendition of Bette Middler's "The Wind Beneath my Wings", which I think is on a single or something.
