Well, being a Bulgarian myself, I was curious about the folklore element. The part at the end of the first video - it felt quite randomly stuck in. It didn’t fit very well. In the second video you used the folk samples much better. Still… breakcore (is this breakcore? it’s at speed 1 so I guess it is ) doesn’t seem a good context for folklore mash-ups. It’s too brutal for this.
So, you score points for the effort, but the result didn’t come out quite right.
P.S. Also, you’d better avoid using what’s probably the most annoying sound in history - ICQ’s “u-uh”.
