(Sorry if I'm not replying correctly, I'm a noob!) That's true, they've always been symphonic, but maybe I mean more of the quality of their production has changed, since Mustis was the powerhouse of their discography. He wrote the songs on keys first and wrote most of the lyrics (he left the band since Shagrath was not crediting him for this). And Vortex's clean vocals were IMO a key element to their sound. They were both the genuine talent in the band, so Dimmu has had to compensate for their loss by, well, becoming more bombastic.
