A3 — also known as Alabama 3 — is the band that plays the theme from The Sopranos, "Woke Up This Morning." It's their sound in a nutshell: blues, country, and a touch of gospel, all over electronic beats, with gruff howling-wolf vocals that sound like they're from Alabama, though the band's really British. But, hey, Tony will vouch for them — you got a problem with that?
