Looks like this could be quite a long running series. Trance Nation 3 was great, so I immediately bought volume four on the day it was released. I was to be somewhat disappointed, though.
Trance Nation 4 is a major let down compared to the previous volumes. As you may have guessed, Kerncraft 400 is the opener, which could sell this album on its own (note that Zombie Nation is the artist rather than the track name - a common misconception). However, this appeared about a year ago on Tranceformer 2000, so it's not exactly "new".
Big commercial tunes are scattered throughout this album, along with several repeats from TN2 and 3 too. Electrique Boutique - 'Revelation', Rising Star - 'Touch Me', Amber - 'Sexual', Delerium 'Silence', and Twister - 'Mauna Kea' have all appeared on earlier volumes of this series. The first six tunes - in fact, the majority of the first CD - are tunes that have appeared or will be on loads of other dance albums. Very few exclusives here.
Out of the tunes that are worth listening to, I've got most of them on another compilation, or on vinyl. The second CD is better than the first for new, quality trance, but overall this is a huge marketing ploy by MOS, who no longer seem to care about the trance content in their flagship trance compilation series. Which is a shame, because I really liked the first three volumes.
It's an above average release, but only worth buying if you haven't got half of the tunes on other compilations. Definitely have a listen to the tunes you don't know before you buy it.
