I do enjoy Age of the Joker and it grew on me a lot over several listens but the last two Edguy albums have been...strange. It's difficult to put my finger on, but I think the sound production and the sort of old school Hard Rock feel to a lot of the songs, even though some of them are good, don't suit Edguy.
On Mandrake, Hellfire Club and Rocket Ride, they were able to change their style and sound less like typical Power Metal and have that Edguy unique quality at the same time.
Theater of Salvation is still my favourite album by them though.
Of course Tobi is making out the new album is the best thing ever and is better than Mandrake, Hellfire Club etc. I somehow feel skeptical about that.
Still, it'll be interesting to find out what it's like.
