It is better to attend another church, if possible, please, don't keep yourself from fellowshipping with othere believers.
Are you the only one with these concerns?
Aren't there other members that have the same reluctance to denigrate worship to a rock concert?
How far is it to the next nearest church to you?
I am fortunate, here, as there are 3 or 4 other churches within 60 miles of here.
My home church is a conservitive one, we do not accept the 'modern' style of worship.
If a Pastor tried it, he'd be out on his ear real quick.
