Seriously? Tell me where you are and I'll find a church for you that doesn't use instrumental music. There are a number of denominations which do not.
I should have been clearer. I meant no music at all. The instrumentation is the least of my problems with contemporary "church music". In fact, many is the time I have sat and wished for the bad musicians to drown out the bad singers and their bad lyrics. The latter are certainly not going to be any better a capella. :D
I could seriously hug you for wanting to help, though. Thanks.
