I am putting together a compilation for someone and am looking for the best acoustic tunes done by prog rock/metal or whatever bands. We're talking wood, strings and voice, emotional and moving stuff. I have quite a few already, some I consider elite and am looking for some more, stuff I've missed out on. I know some power metal bands have recorded unplugged material I'm unaware of, so hit me with it please. I consider Evergrey's Madness Caught Another Victim to be in that elite status based on subject matter and unique tuning. Great song. Stuff like that is what I'm after or even sappy love songs. I've got some Amazon bucks to spend and will be downloading based on your posts. Thanks in advance for any assistance.
