¡Te voy a dar jarabe de palo! is the sort of thing parents used to say to naughty children. Jarabe de palo doesn’t really translate but it’s something like a clip round the ear, ie. a beating. It’s the name of the band but the band is invisible. The guitarist and singer/songwriter Pau Dones is the frontman and it’s him you see on the videos. I like some of his songs very much.
