HOW many times have you been out there on the dancefloor and on comes some bizarre mashed-up track?
These days from Whitney Houston vs U2 and Kylie vs New Order to Justin Timberlake vs Snap, you can barely move for bootlegged pairings that should be so wrong yet sound so right.
Yes, pulling two polar opposite tracks together and making it work is par for the course with any DJ worth his SL1200s. But two guys from Belgium were doing it way before it became a must-have CV skill.
They are 2 Many DJs - aka brothers Stephen and David Dewaele - aka Soulwax.
From Dolly Parton and Royksopp to Gary Numan and Basement Jaxx, Destiny's Child and 10cc nothing is considered too weird a combination for these kings of the mash-up.
"Dolly Parton and Royksopp doesn't sound weird to us - it's all music, it all makes you dance," laughs David.
"Back when we started DJing in 1996 there wasn't really anyone playing the sort of stuff we wanted to hear, they were only playing from one genre of music.
"We wanted to hear music that we could dance to so we started playing parties for our friends and we started doing the mixes that then came to be called mash-ups.
"We never think 'oh we could play this with that', we just play the tracks. It's spontaneous."
This freewheeling, improvisational style could stem from the fact that DJing is not techinically the brothers' day job. It is more a means to an end.
