I normally associate that sort of music with very excited people vigorously jumping and waving and so on. A Royal Albert Hall audience taking a polite interest in proceedings (including what appeared to be a white-haired gentleman in a rather smart tweed jacket) was rather peculiar...
I don't think I've ever watched a pair of drummers closely either. Incredible timing.
I've been on La Cucina myself: https://soundcloud.com/la-cucina
("accordion-driven funky neapolitan rockers"). Music to make you grin like a loony while compulsively tapping on your desk.
