As a confirmed hater of DubStep (yawn), I may seem like not the best person to give a honest review for a CD of the genre, however, I do like to give things a go and that is what I decided I would do for this album.
In terms of what I have heard before, This is DubStep, the Sound of DubStep, DubStep - DJ Picks, DubStep Underground Vol1 etc, this release blows them out of the water by several light-years, whilst the bass isn't as dirty and as deep as I would like it, my stock car speakers handled the different pitches and shifts without any drama, at full blast with the bass cranked up to the max, where as my Gabber and Dutch Hardcore music CDs, kill them at half the volume and at half the bass. Also, a few of the tunes I wouldn't have actually called them DubStep, in particular, track 12: Source 16 - Redlight, I would have said that it was more a long the lines of Bassline, rather than DubStep, so I'm a little confused as to why it's on this CD, but I like them anyway.
The second disc is definitely the best of the release and is worth the money on its own, so essentially, the first CD is the build up, then the second CD is the drop. Whilst I still am not a fan of the genre by any margin of any sort, this release is definitely worth the money being asked for it!
