Yeah, Rush has become a disappointment over the last few years, DJ wise. A man of his age and background could surely be digging deeper, than instead of playing 2 hours of the same loop.
He played a disco set the night before his techno set in Dublin about a month ago, and the disco set was far superior - he really worked the crowd and had a great time himself; wheras the next night he just stayed at 150+ bpm with no progression, and lacked any kind of stage presence like he used to have.
I think Rush is one of techno's real characters, but it's a pity he is stuck in this mould now. He is an icon to younger people coming through so it would be good for him to open their minds a little... or even a smidgen.
