Commercials can be very similar to music videos. An example are the short films made for advertising iPhone XS. FKA Twigs, Kamasi Washington and Florence + the Machine all have each a short music video shot with iPhone XS. Of course to show the quality of the camera in the phone. The short films are all back stage/rehearsal scenes. Nice glimpses of the artists behind stage.
Some artists aren’t afraid of showing controversial things in their videos. In FKA twigs “Video Girl” directed by Kahlil Joseph you can see the execution of a death penalty by poison injection meanwhile FKA twigs dances around. Could be just provocative but the style of the song in combination with a superb production makes it a captivating video.
