I play guitar at our Church,I am alone mostly,I do not play amplified,no other instruments.......I do know,what you mean about the "twang and bang"thing you mention,wherein the only thing accomplished,is the creation of a lot of annoying noise.Real music in Church is NOT how loud and annoying you can get,Some have forgotten that.....The MESSAGE you are conveying,is #1 priority......There is a song I will be doing this Sunday,to address all the murders/ suicides,that have been taking place in our area...It is done by the Eagles...Not a Gospel song per se,but a great message,entitled"HOLE IN THE WORLD".......There's a hole in the world tonite/Theres a cloud of fear and sorrow/There's a hole in the world tonight/Dont let there be a hole in the world tomorrow"......Just me and my guitar,nothing more......Sometimes,the less noise you make,the better off you are...
