Fox has released the first trailer for Alter Ego, a new TV competition in which singers channel their voices through digital avatars. Grimes and Alanis Morissette are joining Nick Lachey and Will.i.am as judges on the show, which premieres September 22nd. Check out the trailer below.

Earlier this year, Grimes appeared on an episode of Saturday Night Live hosted by her partner Elon Musk. Previously she was involved in a “Grimes and Punishment” sketch on the Eric Andre Show, in which she was subjected to a kitschy “torture” by the duo Kraft Punk. Alanis Morissette is currently continuing her planned tour through the USA for the 25th anniversary of her album Jagged Little Pill.
