Hi
It always worries me when I see a band/performer bring their own sound person. They never seem to get a good sound-maybe it has to do with trying to operate someone elses equipment.I've seen a sound man do an amazing job,all week, at a festival venue dealing with all sorts of performers- then a band insist on using their 'sound person'-who has never been in the venue before-and does a sound check for his band halfway thru the evening and makes a complete hash of it. Isn't there some justification for a bands own 'sound person' to advise the real sound person as to what sound the band/performer wishes to achieve and then let the 'real' sound person get on with it and use their experience of the venue.
