A vest frottoir or rubboard is a percussion instrument used in zydeco music similar to a washboard. It is usually made from pressed, corrugated stainless steel and is worn over the shoulders.
It is played as a rhythm instrument by stroking either bottle openers or spoons down it.[1] Many of these instruments are home-made, but Don Landry of Louisiana is one professional maker, making them for Clifton Chenier's band and Elvis Fontenot and the Sugar Bees, amongst others.
