I remember (However hard I try not to) a 1970's folk-rock 'concept album' entitled 'When God's on the Water - A Musical Journey Down a River from Source to Sea'. It was TERRIBLE. I still sometimes wake up in a cold sweat having had a flashback of the heavy rock treatment of 'Marrowbones'.

The band involved (Which had some unpronouncable and pretentiously twee 'folky' name, as I recall) actually got a contract for a second album from a (presumably tone-deaf) producer but after that thankfully vanished into the 'where are they now?' bin.
