Review: George Acosta Feat. Tiff Lacey – I Know (Beat Service Proglifting Remix) (Trance) Drew Wilson | December 18, 2017 This review covers the progressive trance track George Acosta Feat. Tiff Lacey – I Know (Beat Service Proglifting Remix). This track was released in 2010 along with 6 other versions. One great element in this track was the vocals. They were very nicely done because they have that soothing sound to them. What helped them along were the pads that backed them. To balance things out was a melody that faded in after the vocals. This main melody evolved nicely and gave this track a very nice sound. When both the vocals and main melody overlap on the later portion of the track, this track sounded great. The brief submelody that appears from time to time really added a nice touch to the overall sound. The occasional chopped vocals also worked quite nicely in this case. It made the final breakdown a pleasant listening experience. Overall, this was a very good track all around. It has great vocals, great melody, nice sub-melody, and well done effects like the chopped vocals. This is yet another very good track to listen to. Score 7.5/10 Drew Wilson on Twitter: @icecube85 and Google+.
