Sigillum S

[13]

I am well-acquainted with Atrax Morgue, Maurizio Bianchi, Mauthausen Orchestra, Pietro Mazzocchin, The Sodality etc., but I have somehow managed to neglect Sigillum S completely. Browsing through the Verba Corrige catalogue, I noticed that they have several releases with the band and they all look delicious. So my question is, what is generally considered the essentials?

This has always been a favorite:

Bardo Thos Grol, splits with Gerstein and Ain Soph

The band informed me the earlier material will be getting a vinyl release in the near future.

Bardo Thos-Grol [1987] and Dispersion: Sliced Carrions And Pixel Handcuffs [1991] cover my Sigillum S needs these days.

The earlier stuff is mandatory in my opinion. Later on, they've started to experiment with electronica, dub and implemented a "cleaner" and more surgical sound.
The 3 releases they put out for the 30th anniversary are a good way to describe their path and evolution (LP+Tape+CD).
