Groove Stick
1980s
Bang the drum, work that cymbal, but you can only do one thing at a time.
These double drumsticks have been in our storage for a long time. The inventor’s basic idea was that you could play the hi-hat cymbals twice as fast by hitting them both on the downstroke and upstroke.
The problem is that you can’t play anything else - namely a drum - with the drumsticks. Musicians never did find them groovy, but we get happy every time we see them.
