Easy Star All Star's "Dub Side of the Moon" is also done with a lot of respect for the source album (and not a hint of 4/4 transposition). [1]
Les Claypool's Flying Frog Brigade also covered the entirety of the Animals album as the second half of their live set which is also obscenely respectful to the original and actually benefits from Claypools heavy bass driving it. [2]
If you enjoy bluegrass covers, then Hayseed Dixie are worth a look at :) [3]
They've done a fantastic bluegrass revision album, "Dark Side of the Moonshine". Well worth a listen if you like PF.
