Reddit mentions of Rebuild the Wall

This is really good. Bluegrass isn't my favourite genre, but when done well, and against other compositions like this, I find I sometimes really like/respect how it's done. This actually does an admirable job. About the only negative would be that there's no real break in it to emulate the change in dynamics from the original. And yet...it still works, so it's not really a negative. This may be one of the best covers I've heard, possibly because they're not even trying to emulate Gilmour's playing.

If you like this, you should love this album (note that you can get it at the cheaper prices used...that new price is insane...it was $14 when I got it):

I was pretty bummed out about it.

What's weird is that Pink Floyd seem to be the progenitors of a whole new subgenre of covers: Covers of entire albums. I have three.

• Rebuild the Wall, by Luther Wright and the Wrongs, which is an astonishingly good bluegrass rendition;
  
  
• Dub Side of the Moon, a reggae/dub take on DSOTM. Fun bit: the repeated song starting "Money" is a bong bubbling instead of a cash register.
  
  plus the Lips one.

The famous (within the bluegrass community anyway) Bluegrass band Hot Rize would alternate sets with their alter-egos Red Knuckles and the Trailblazers, a kitschy country band.

While Hot Rize would perform in the traditional suitcoat style that many Bluegrass bands would wear, Red Knuckles wore lots of fringe and bright sateen shirts - he even had fringe on the neck of his guitar. Red Knuckles would also rag on Hot Rize for playing that "itchy scratchy" music - which was what the audience came to see.

Red Knuckles was damn entertaining, with excellent musicianship, humor and a willingness to try genres and do covers of other bands, something that the purists would wail and gnash their teeth if Hot Rize tried. Red Knuckles actually did a fake commercial a'la late night television for an album of rock and roll standards in a traditional country style (Not Shania, more like old Johnny Cash or Merle Haggard). The song that comes to memory when I reminisce was "Hey Joe" done to an upbeat country standard.

Of course, if you find that interesting, I highly recommend Luther Wright and the Wrongs song-by-song cover of Pink Floyd's "the Wall" Album done in a country/bluegrass style.
