Wavves’ Nathan Williams is totally down with big-business brand integration. Remember when he and girlfriend Best Coast recorded a duet for exclusive release on Target’s Christmas compilation? And how about his “Post Acid” video, created for Mountain Dew? Well, now Williams is lending his cred (such as it is, at this point) to MTV, which has hired him to score a new scripted series called I Just Want My Pants Back. The show is based on David J. Rosen’s novel of the same name, follows post-college types living in Brooklyn, and will feature around 20 original pieces by “guest composer” Williams, in addition to songs from his band’s upcoming EP, Life Sux. According to Joe Cuello, MTV’s senior VP of Creative Music Integration, Rosen’s book is “saturated with hipster music and how it relates to these people,” so it’s essential in telling “the story of the coolest crowd” to get “an affirmation from the people who provide the soundtrack.” If you’re interested to see how this works out for all involved, you can watch the pilot after MTV’s Video Music Awards Sunday.
