best vocal harmonies in rock

Lyle Lovett/Rickie Lee Jones on Joshua..., Both Trio Albums: Ronstadt/Parton/Harris, Bruce Cockburn/Lucinda Williams (Isn't That What Friends Are For?), the Streisand/Gibbs album, Mark Knopfler/Emmylou Harris (at times), Linda Ronstadt/Aaron Neville, K.D. Lang/Martino. Admittedly, none of these are long term pairings but the work they occasionally did together was wonderful.

Just some off the wall suggestions to add to the superb obvious choices already given.

great stuff.

but let's hear it about music from _this_ century, too! ;-)

x2 Veruca Salt. Matthew Sweet. Dandy Warhols. Fountains of Wayne....

From my perspective, no one mentioning Van Halen needs to apologize (and I'm f'ing old). Those high vocal harmonies by bassist Michael Anthony are wonderful and contribute to a signature sound. Don't know if that constitutes a "best" but sure is nice.

My Gosh, America didn't get a mention yet!!
