MALIGNANT TUMOUR(cz) will perform at Party.San Open Air 2012! Well, Rock n Roll, Grindcore, Crust, Punk, Heavy Metal, more Crust, more Heavy Metal, and then some more Grindcore. Topped off with more Grindcore and then again more Rock n Roll. This is what MALIGNANT TUMOUR is all about! You need to see this band live to understand their concept but you can be sure that this is a lesson in entertaining music for true metal heads.
