In this video “Grandpa Al” reacts to his grandson’s dubstep electronic dance music. At first he’s not sure what to make of it, but by the end of the video he is enjoying it saying it has a nice dance-able beat. Grandpa Al, must have been a cool guy back in the day. He was probably doing the same thing, playing the beginnings of rock ‘n’ roll to his grandfather with a similar reaction. History has a habit of repeating itself.
