Best Tributes, Covers, Dedications

There have been some fine tribute, cover, and dedication albums. A few examples in pop include:

The Bridge-A Tribute to Neil Young
Hank Williams-Timeless
Till The Night Is Gone-A Tribute to Doc Pomus
Shangrila-A Tribute to the Kinks

I would include albums of original material in which the dedications are presented thematically, like Lou Reed's "Magic & Loss"(Doc Pomus), or Lou Reed with John Cale "Songs for Drella"(Warhol).

The idea could be stretched into a general list of "best of" cover albums. I nominate Matthew Sweet's recent "Under the Covers Vol. I & II.

Any other good examples in pop, jazz, or classical?
