There are 2 Artists under the name Tumor a) TUMOR was founded in 1998 by Chris Pohl who is also known for his bands Blutengel, Terminal Choice and Seelenkrank.
He was looking for an output for his more strange and agressive ideas in music and mind.
Those would not have fit in one of his other projects so he created TUMOR to live them out.
Tumor is electric dance music with a touch of electro and always with some samples from different movies and a crazy sense of humor. The first album was limited of just 1000 copies and created just by himself.
