The Rat-Off series is a collaboration between talented and extraordinaire Belgian drummer Teun Verbruggen's Rat Records label and Off.
It all started with the release of Caca and then continued for more complex and beautiful avant-jazz / noise / modern music.
Some releases are both physical and digital, while for some, Off takes the digital part in charge.
