I recommend a listen to that Kode9 mix (linked below). Love the Ghost Town cover it starts with. And a lot of other good stuff.
On the other hand, if you're expecting Rolldeep, Riko and Lady Sovereign, then you're in the wrong place. Kode9 seems to be part of that whole "intelligent" grime / dub-step thing like the Rephlex "Grime" compilation last year.
Update: 23 mins in, he plays Rolldeep ... :-0
