Sanka (2) and Dreadlock are two aliases that were used by Eugenio Dorwart & Matthijs Hazeleger (Bass-D & King Matthew) to sign the writing of Stoned Fever tracks, and later, the co-writing on two Masochist releases. It is however unknown which alias was meant for Eugenio and which one was meant for Matthijs.
Eugenio and Matthijs also wrote some Gabber Piet tracks as Sanka (2) and K. Ramba.
