Listen to the first part of this. Which is Adam Gussow schooling us on Sonny Boy Williamson.
Then listen to the beginning of this. You don't actually have to get more than ten seconds into it. Just the "Down Down Baby, Yo' Street in a Range Rover" part.
Nelly's rockin' the signature riff to "Pontiac Blues". Rockin' a different set of wheels, to be sure, but it's the same riff.
Nothin' new under the sun, I guess.
