And I can't leave out my favorite interpreter:

Frank Sinatra

BIGOD 20, an industrial band, did a fantastic remake of Modonna's "LIKE A PRAYER"

I think KMFDM made a remake of Modonnas "Material Girl" as well

hahahaha

probably not what yer looking for, but i thought they were funnier than hell!

Johnny Cash does some great covers as your already aware.

His American Recording albums and the Unearthed box set are chuck full of 'em.

Be nice to me and I'll send ya the box set for review.

The Australian band The Church (Best know "For Under The Milky Way"), their 1999 release of A Box of Birds. They've been very clever about their choices; only Mott the Hoople's "All the Young Dudes," Hawkwind's "Silver Machine" and Neil Young's "Cortez the Killer" are covered regularly by other bands. The remainder of the songs — ranging from the Beatles' "It's All too Much" and the Monkees' "The Porpoise Song" to Kevin Ayers' "Decadence," Television's "Friction," Ultravox's "Hiroshima Mon Amour" and Iggy Pop's "The Endless Sea" — aren't obvious choices, which give the record considerable character. The Church don't really reinvent these songs, choosing to remain faithful to the tenor of the original while retaining their own signature sound. The end result may not be revelatory, like the best covers albums, but it is fun, and the band sounds like they're having fun, too.

Richingoth,

Thanks for the tip. That's exactly the kind of off the beaten track type item I was looking for. An lp that contains a cover or two is one thing, but an lp that's chuck full of interesting covers is another.
