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?
