Blaine fiddled with the dial on the radio, trying to find something with a decent beat that they could work with. Brittany was stretching leg practically touching her head in a pose that reminded him of a ballerina. She tended to fall over when she tried this, so Mike was spotting her nearby. Artie for his part was setting up his camera, ready to record once they got started with choreography.
The commercial playing faded out and a heavy club beat filled the living room. Blaine grinned at the other two, Brittany now bouncing on her toes to prime herself for dancing. Mike cracked his back and stepped right into the moment, moving with the music and not paying attention to what he was doing. Blaine and Brittany joined him, trying not to bump into each other and somehow managing it. Artie pulled the video wide, trying to catch everything they were doing.
Mike was the one who came up with this "brainstorming" to help choreograph numbers for New Directions. It was Artie's idea to film them. None of them would have thought of some of these moves if they hadn't seen their own selves doing them on the screen.
