The Recording Academy uses the two weeks prior to the Grammy Awards to announce performers and presenters and executive producer Ken Ehrlich says Thursday should yield a "major interesting" announcement. Ehrlich tells Billboard that this year's telecast -- 8 p.m. Feb. 12 on CBS -- will feature 17 or 18 production pieces with about 22 songs being performed. "Arguably it's one of the biggest shows" in the history of the Grammys, he says.
