sharkey is a true legend in the world of hardcore/freeform, his tunes are wicked and his freeform sets kick ass but i'm not too sure about him mixing hard trance. heard a few good hard trance/techno sets on a darker tip but only time i heard him play out live his mixing was a tad sketchy. he looked a bit mashed though so probably why!
what he does well is build his sets. heard him play a set starting with bouncy hard house into more uplifting trance then into hard trance then finishing off with some mindblowing trancecore. he really knows how to read the crowd.
