What could be more flashback than a song from 1997 being covered in a style from the 50s? Not much.

For those of you who have not been on the internet ever, Postmodern Jukebox is a collection of musicians who revamp songs and make them super cool. They have done really awesome retro versions of songs by everyone from NSync to Soundgarden.

Well, of course I got totally excited when I saw that they covered Hanson's "MMMBop."

Beautiful four part harmony accompanied by awesome musicians. And I gotta say, I know I shouldn't judge a book by its cover, but when the smallest of the four guys does the bass part, I was shocked. So good!
