Probably two of the biggest DNB artists over the last 20 + years. I think it would be really interesting seeing them in the space environment rather than together at amnesia.
I was massively into DNB in my younger days and these two play very different styles.
Carl Cox used to do Fantazia etc with a load of the big (now) dnb djs such as fabio and grooverider.
Andy C - more upfront but excellent dj (though does play a lot of cheese now) - excellent atmosphere when he plays.
LTJ Bukem - is a pioneer of the liquid variety of drum and bass - this is such a beautiful tune
