Twangin... consists mostly of outtakes from previous recording sessions, including one track dating to 1968, a version of "Baby Let's Play House", a rockabilly number made famous by Elvis Presley. The album also features a collaboration with the Stray Cats, whose debut album Edmunds produced.
The album is almost entirely made up of cover songs, including the Wilson Pickett B-side "Three Time Loser" and the George Jones classic "The Race Is On" (with the Stray Cats).
The album art, featuring a portrait of Edmunds, is by Barney Bubbles.
