The songs on 'Weltformel' seem a bit scattered with longer instrumental sections than I'd like. The use of synths is to be expected but are overused in my opinion. There are some really solid guitar pieces throughout and the vocals are solid black metal style rasps. It feels a bit disjointed at times and was really hard to focus as there was quite a bit going on through each song. If things had been shortened up a little bit and had a bit more sound structure to them, this wouldn't have been as difficult to get through.
