Too often, it seems that music videos, especially animated ones, need to be elaborate — and ideally computer generated — to impress: Witness Kanye West’s state-of-the-art, rotoscoped mini-movie for his latest single “Heartless.” However, artists like London’s Roses Kings Castles prove that there’s still plenty of room for the homespun and hand-drawn when it comes to animation and music videos. A robotic couple, a city with gear-driven sidewalks and streaky magic markers make up the utterly charming clip for “Entroubled” from Roses Kings Castles’ self-titled debut album. “Entroubled”’s cheeky chappy pop sounds more than a little like Babyshambles, which makes sense considering that Adam Ficek, the man behind Roses Kings Castles, is that band’s drummer.
