Robin Thicke performed “Blurred Lines” with the unlikely accompaniment of T.I. and a few members of Earth, Wind & Fire at the CBS Grammy Nomination Concert, hosted in Los Angeles on Friday night. The singer notably abstained from dressing as a nightmarish Footlocker associate and opted to grind with the guitar player in lieu of scantily clad models.

The unofficial song of the summer was, once again, the highlight of the evening, despite the fact its long-winded controversy including a lawsuit from the family of Marvin Gaye as well as criticism for its blatant allusions to date rape. In addition to performing, Thicke received nods in the Record of the Year, Best Pop Duo and Best Pop Vocal Album categories. A trophy in January would be the first for Thicke. The 56th annual Grammy awards will take place at the Staples center in Los Angeles and air on Jan. 26, 2014, also on CBS.
