Acoustic metal?

Anathema have put out two acoustic based albums. The first being Hindsight which is some of their more recent material. Falling Deeper is the second and features acoustic versions of their earlier material.

No mention of Tourniquet's Acoustic Archives? Horrific album cover but a pretty good disc.

To me an acoustic version can show the true strength of the song writing. A few years back VH1 put out that 3 disc set of acoustic versions from the big hair acts of the 80's. I thought it was a really fun listen since stripped down some of the songs came across even sillier while others revealed some pretty strong writing that got lost in all the studio dressing those records had.
