As Peter said in some Interviews, Horgh is one of the Reason why they play so much other Songs this time. Horgh learned to play the whole Songs Hypocrisy made over the Years. Lars wasn't able to do some of the other and old Songs any more...
Live, they played the old Songs like God is lie an Necronomicon kind of old-school. You all know, that they play Songs like "Pleasure..." or "Osculum" a bit different then in the old days. But with Horgh they play it more old school, and the don't play the Songs the most people expect to hear live... like said at the beginning, Peter said that this was Horghs Influence...
Horgh plays the Songs very powerfull and very perfect. At the Gigs I've seen he added some new parts (I'm no drummer, so I don't know how to explain it the right way what exactly he does...).. some bassdrum party, some with the tombs in the slower section of a Song...
He plays more old-school style, but its kind of fresh... you can hear that he has fun to play it... with Lars it sounded like "Ok... lets play it again...".. Lars is a great drummer, too... but he didn't sound that "fresh" any more... I looking forward to the next Album... with Horgh on Drums...
