Query: Great progressive trance/house CD

This is definitely a nice solid progressive sound CD. It starts off very mellow and then by track 4 builds to that great 4am music. Andy Hughes then takes it up and down through peaks and valleys, but in a smooth way. He does a great job in using some remixes that have 'haunting' vocals. Some points towards the end arent as "thumping" as I usually like, but still has enough energy. Definitely a good pick if you like the progressive sound found at many raves today.
