Both mixes of this solid Renaissance release were included on the compilation.
 
Full review here:
John Digweed has set such a high standard with his previous releases in the Transitions series, that it was always going to be hard to beat with Transitions 4. However, I think he might just have done it.

Don't expect more of the same as Transitions 1 to 3. This one is an altogether more intricate mix, with no less than 22 tracks crammed in to its 73 minutes. And musically it is a darker journey as well. Digweed has cut down slightly on the uplifting melodies, and instead focussed on more bass-driven and percussive elements. The style still sits somewhere inbetween progressive and techno, but this time definitely leaning more towards the techno end of the scale...
