ETA: Just thought I'd add the fact that there is now a facebook page: http://www.facebook.com/drummersbehindglass you can like and have the latest posts just show up without having to seek them out.
The fracturing and bloody crusades against stage volume have had many casualties. One tragic outcome is that drummers are no longer allowed to be in the presence of other band members while playing. They have to be segregated. Sometimes by some leaning plexiglass sometimes by entire rooms built to keep them away from the rest of the team. If you won't or can't undo this wrong, you owe it to your drummer to at least acknowledge it.
Here is the opportunity to do just that. At this weekend's service photograph your drummer in his cage, behind his shield etc. Then go to http://drummersbehindglass.com and click the submit image button. If you just don't do something to bring awareness to this issue you are propagating it. Hug a drummer this weekend. They are musicians too.
Yes yours probably isn't this fancy but it's your drummers unique "home on stage."
