That sounds a lot like steel guitar. The high-end ones have a row of foot pedals for changing pitches, and also knee levers. So a guy is picking the strings with a hand full of finger picks, and using the bar and trying to eyeball it over the frets for pitch. Granted they can slide around a lot but as they advance up their their competitors rip them to shreds for playing out of tune, sort of like blowing flat if you play sax.
