I can’t even remember the last time I saw an ad for a new album that wasn’t the typical generic commercial that showed a clip of the video, etc. So leave it to Eminem to go against the grain and parody the Sham-Wow commercials to promote his upcoming album “Recovery” (which now arrives on Monday, 6/21. The release date was moved up a day to combat rampant leaks). I gotta give it to Em, this ad is a stroke of genius. By almost all accounts, the album is a great return to form as well. Other artists should be so creative.
