The Madhouse Brothers make some of the best hard Techno around (imo)
I came across their music after ripping loads of Paul Birkin off Youtube, I've been lucky enough to hear them live too. They played the 5am till 6am set which is kinda fitting to their style.
Check this mate, I love this track myself. more Funk than James Brown, more swing that something that swings & more acid than a p.h. of 0. It's just one of those tracks you never forget once heard.
That Witch House you picked is great too, I'm so fussy when it comes to this style of music as a lot is terrible but he does some really great stuff & it is one of those producers you never forget about once heard. Check the video on this, the lyrics are great too.
