They are called Scott Bradlee and the Postmodern Jukebox and they take popular songs that are on pop stations like 94.9 and redo them in vintage styles from the big bands of the 30s to the doo wop of the 50s. Every member of the group is brilliant. The pianist is wonderful and they have some horn players that, oh, oh they are good. I am so used to the roar of electric guitars and pounding drums and lyrics that are more spoken than sung, that it is really neat to hear the same lyrics completely redone. Take a listen.
Oh! And bonus, they band members dress up in the style of the day that they are mimicking!
