It’s much, much easier to make a case for the B-Side of Falco’s smash-hit “Rock Me Amadeus” as a bizarro, hopped up seven-minute odyssey than it is to convince anyone that it’s, you know, actually good. And yet, the new wave scat-rap of “Urban Tropical” is more than good. It’s the jam — a jam with the added bonus of eliciting a collective (if predictable) response of: “THAT Falco?” That Falco, indeed.
