Only been DJing for about 6 months and use an M-Audio Xponent controller for my laptop. I would use vinyl but couldn't build up a vinyl collection as big as my iTunes library without spending a lot of money...

I mix Drum & Bass, mainly liquid, but dabble in other areas as well :)

There are more of my mixes on my SoundCloud account...

...and on my YouTube channel...

...but will only be using this site from now on.
