I love them live. I've seen them twice in VA with only 30 others, once at Nearfest, once Progday, and once more in VA with about a hundred. Never disappoint!
Hasse is a great singer. He makes no pretenses about being able to play the guitar...he can ham it up, but he's needed for the soft songs too. There's so much talent in the band that he gets lost. I could watch Jonas and Tomas all show (when they did Garden of Dreams I watched his keyboard the whole time

)
So much more to say..but I'm happy to hear how they are in Europe, where they play so much more (and rightly so).
I'd venture to say they are the greatest prog band since they began.
