Favorite Cover Album

I particularly like the French duo who goes by the name Nouvelle Vague.  There self-titled album is particularly good.  They primarily cover Brit Pop.

For the really outrageous, so bad it is interesting, I suggest:

Pat Boone (Christian music) doing weird jazz band covers of heavy metal, the album is called "No More Mr. Nice Guy" (he is wearing leather on the cover art).

How about "Sebastian Cabot, Actor/Bob Dylan, Poet" (the actor does a dramatic reading of Dylan lyrics while truly awful versions of Dylan's music plays in the background.

For individual tracks, check out Klaus Nomi: "Just One Look"

And then there is Yoko Ono doing Adele:

Another good cover album has various artists covering the music of Richard and Karen Carpenter.  The album is called "If I were a Carpenter."  I particularly like Shonen Knife's version of "top of the World" and Redd Kross' version of "Yesterday Once More."

Another favorite of mine, for awesomely awful covers is the CD called “Golden Throats: The Great Celebrity Singoff.”  It includes two William Shatner numbers: “Mr. Tambourine Man” and “Lucy in the Sky With Diamonds”, Mae West doing “Twist and Shout”, Andy Griffith doing “House of the Rising Sun”, and a whole lot more.
