Frank Kaumanns has 3 Rabia Sorda concerts.

Rabia Sorda is Erk Aicrag's solo project. The lyricist and singer of the Mexican hard elektro duo Hocico, started working on this project in 2003, listening to the internal voices that compelled him to create his own sonic world. To create, he sees himself from a different perspective and he reinvents aspects of himself to bring this new entity to life.
