the kick rythm and the reverse drum sample sound nice but definitely take away from the hip hop vibe. Something a bit simpler but with more groove would work better for that. At the moment sounds a bit idm-ish which is cool but not what you’re going for according to your post
I heard some reverse drum sounds in some xhibit intstrumentals but I guess thats more hip pop than hip hop. I get what your saying, I am sampling pop cd’s not just jazz and soul. Thanks
