U obviously attend these types of events for a different reason than me then.... cause it isnt just for a "dance" for me....... I attend purely for the music, so i would be expecting an excellant sound system. And with the billing it had, it should have been a superior system to most imo, so having a channel missing and a severe lack of bass is a disgrace!
p.s. £30 is a lot of money for me! then included the expense of a 600mile round trip as well if i was able to attend.
