a number 1 is tough but honestly I would have to say Dream Theater.
New ""Airbag" is a close 2rd...........
Pandora - Alibi Filosofico
Pandora's second album was very much in the traditional Rock Progressivo Italiano style but for their third album they created a more original and interesting variant of RPI. They even have Arjen Lucassen as a guest on the second track.
For me its one of the more inventive releases of 2013.
Thanks for explaining the differences from the 2nd disc which I was going to get...
