My issue is not that syncing = bad. […] In the Lisbon club scene, DJs use free software to sync tracks with incredibly complex rhythms—usually tracks that were produced by the DJ or one of his or her crew—blending them together at breakneck speed. The best DJs in the experimental club music style move rapidly between genres and tempos using CDJs, their sets rarely adhering to standard beatmatching.
[…] There is, of course, a whole […] side of DJing that aligns itself closer to live performance, a style of which Hawtin is an advocate. DJs like Surgeon, Paula Temple, Speedy J and Chris Liebing use individual technological solutions to do things that are not possible with a standard CDJs or turntable setup. When this style is done well, the DJ is, in effect, improvising, pulling tracks apart and reassembling them in new and interesting ways. My feeling is that more could be done to audibly show the audience how this technique affects the tracks and parts of tracks that are being played, but regardless of this, there’s no question that syncing the music is vital to this type of performance.
