best vocal harmonies in rock


What r'n'r artists (or records) feature great vocal harmonies? To keep the list more manageable, let's stay with the post doo-wop period. Brian Wilson/Beach Boys, Todd Rundgren/Utopia and Lindsey Buckingham/Fleetwood Mac -among others- all qualify in my book. Who do you like?

Since most of the responses seem to be so focused on acoustic music, I'll throw out something more recent:

Nickel Creek

At least in this decade, they were unsurpassed when it came to vocal harmonies...
I bow to the person who mentioned the Bee Gees. VERY unfair that it took us over 30 posts.
What about Teenage Fanclub? They're frequently compared to the Byrds and are affectionately referred to as the Bellshill Beach Boys because of their vocal harmonies.
