"Excuse me, but is one of those gentlemen playing a fricking THERAMIN?!"
It's a single-string (monochord) instrument called a "dan bau," that sounds a LOT like a theramin,
Check out the guitar. Vietnamese players use guitars with heavily scalloped necks. Instead of just bending strings up and down along the fret like other players, they can push the string into the fretboard for a different kind of bend.
