Audix has released the first in a series of three videos that showcase proper vocal microphone technique.  This video is a must-watch for members of your band or worship team, especially new members.  As you know, you can try to teach people about microphone technique yourself, or you have a video from an outside source say the exact same thing and they'll buy it -- hook, line and sinker. 

Please make use of this tool provided by Audix.
