It's "Art", don't you see? Just like a million other music video's, since the artists (film) can't just show the band playing the music. I recommend then Dwight Yoakam's unarty videos: http://www.youtube.com/watch?v=qfVSHjh8kwo&list=PLITGm4Kdqbogeh2xF4f_M7Uv01Su_y6HL&index=3&feature=plpp_video
Yeah! The only art Dwight needs is his music!
Still remember the first time I heard Guitars Cadillacs, that song just blew me away.
