Sander k incorporates a lot of trance elements in his sets but he is not considered progressive trance dj. He is very versatile dj so it is really hard to label him. He's actually always been known as progressive house dj who plays some trance in his sets. If you listen to all of his comps nubreed, essential mix or that last one..it is mostly funky,progressive house with some trance tracks mixed in. I actually used to be a big fan of his when he played at arc. He always brought a good vibe to the party and lots of hot chicks would come out. I really enjoyed his sound at that time because it was fresh and funky.
