I think that when great artists in a given genre attempt musical efforts in another style the results are often a disaster. Examples are, Willie Nelson "Countryman" (reggae), Van Morrison "Pay The Devil" (country), Paul Simon's and Sting's recent "classical" offerings - I have blissfully forgotten the titles. Anything by Edgar Meyer and any jazz outing by Yo Yo Ma, etc. It seems classical artists playing jazz make for the most wooden of all performances, the lack of structure seemingly working against decades of training.
The exception to the whole phenomena is Pat Boones "In A Metal Mood. No More Mr. Nice Guy" in which he covers the heavy metal canon, including a salsa tinged reading of "Stairway To Heaven" and an indescribable interpretation of "Smoke On The Water".
