Hell yeah, I'd say so. Their early stuff is more symphonic death metal, but their recent material is a very classically influenced, mature symphonic sound. In my opinion, the albums to check out are Deggial, Secret of the Runes, Lemuria/Sirius B, and Gothic Kaballah. They had a few albums before Deggial that were great too, but my favorites are the more recent stuff.
That album is fuckin' sweet. Trul is one of the coolest songs ever, I think. It's rare you find a song with no actual words in the chorus, but still one of coolest choruses I've ever heard.
