In 2001, SITD also released their largest hit single to-date, Snuff Machinery, which made liberal use of sampled dialogue from the German dub of the film 8mm, a 1999 US thriller dealing with snuff films.

In 2003, Francesco D'Angelo joined SITD and they released the EP Laughingstock and then the full-length album Stronghold.

In 2004, they performed at the Zillo Festival (with Skinny Puppy), and the Elektronisches Hilfswerk Charity Tour with VNV Nation, Combichrist and NamNamBulu.

By the end of the year they were in 3rd Position in the Top Single Act National category for 2005 on the Deutsche Alternative Chart (DAC).

The limited edition of this album featured a 2nd CD compiling a number of remixes SITD had assembled for other bands over the years.
