I was raised in a household of fifties-lovers. My dad was a DJ and my parents pretty much thought their highschool days were the best. Needless to say, I know pretty much the entire catalog of late 50's-early 60's songs.
My MP3 collection is pretty massive these days and I was sitting there listening to Postal Service when Everly Brothers came off and I was like - huh, minus the electronica, they have sort of the same sound . . . and I started to screw around and was like, hmm . . .
So then I played some stuff for my parents (Wilco, Deathcab, Old 97s, OAR, Neko Case, Pete Francis, etc) and they really, really liked it. My parents like nothing but oldies and Andrea Boticelli.
I am not a music snob, and I am not obsessed with labels and history, so I hope someone out there can draw the connection I think must be there . . .
