Almost every musician has heard the tale of the grumpy sound engineer; some say it’s a myth while others swear it is true. I am here to assure you that it is 100% real. The grumpy sound guy usually lies dormant but can easily be provoked to the point of no return. There are no specific rites of invocation for this dreadful beast; no gesture is negligible - the beast heeds them all so be careful or you may end up with more than you bargained for. Every time a singer cups his microphone, every time a guitar player pulls up the amp volume, all those times the drummer positions his stands on the cables - that is when the demon wakes from its slumber.
