Tales from the Twilight World is, in my opinion, one of the biggest jumps in quality from album to album ever by a band. Especially considering it is only one year after Follow the Blind and features the exact same band members, of whom all are performing significantly better (on top of the overall better songwriting and overall production).
And the songs of Tales are ace live. It is before Hansi goes into overdrive with his vocals, making pretty much all of the songs fit Hansi's voice without notable compromise throughout his career thus far (on top of the two albums prior).
And yes, the drumming is great, Thomen is actually one of my favourite drummers. Especially his work on Nightfall in Middle Earth. I like Fredrick live, but his studiowork doesn't hold a candle to that of Thomen.
