In fact, even though it look weird here on discogs, the information is correct. On the first 3 tracks PvK helped me out, and the last one is by him alone. That's why I'm only mentioned as additional artist, even though it is my own e.p.
What might look better is if it was added to the normal credits, and then mentioned as A1, A2, B1.

Меня это несколько удивило. Хотя первый релиз + на обложке так и написано. Общем в итоге:
A1 Trypticon & DJ Ruffneck - Soul Reaver
A2 Trypticon & DJ Ruffneck - Sumtimez
B1 Trypticon & DJ Ruffneck - Mixmasta
B2 DJ Ruffneck - Step Aside!

А к примеру на обложке http://www.discogs.com/release/211850 об этом не сказано)
