Your mileage may vary, but I liked the fact that, while the discs still cover different styles, from the most tuneful and enjoyable selection by Scott Brown that I've heard, through Kevin Energy's towering epic of a mix, to Joey Riot's thoroughly bouncy ball of cheerfulness, there is a feel of unity to the compilation. Some old trance favourites make their appearance in flashy and sometimes quite twisted, new clothes, in amongst the newer material, so don't be fooled by the familiarity of some of the titles in the tracklist!
One of the discs is bound to appeal more than the others - for me it's easily the frenetic trance-infected hardcore set by Kevin Energy, with its consistency of vision, and emotional intensity, and subtleties in the production. He and Sharkey in the Bonkers series are bringing a degree of sophistication to the genre that some listeners might view with a little suspicion, but I'm finding myself looking forward to what their next moves could be. It's not just dance music.
I thought Volume 3 in this series was a great collection, but after a couple of listens I'm picking this as the highlight for the year so far.
