all over dude they rip things from movies old tapes video games. sample something original you can turn pretty much any sound into a kick snare and hat if you know how to use a sampler. as mentioned compression is huge for these guys it basically is the aesthetic for their tracks most of which they do with racks/hardware. i read in an interview samiyam got one of his fav snares from like the noise of a zombies head being smashed in some old video game. these guys are all about having fun. so have more fun and worry less about your sound it'll take care of itself. and def stop worrying about how other cats sound.
