I'm guessing it will be the ordinary red & cyan glasses. Usually, for 3D events or shows the company will put something up about what glasses you'll need on their website.
*EDIT* - Just found this on the website...
"CBS and Target have partnered to provide millions of free 3-D GRAMMY Glasses. From Sunday, Jan. 24 through Sunday, Jan. 31, Target stores nationwide will exclusively offer these 3-D GRAMMY Glasses so that fans have the opportunity to see the film that was very personal to Jackson. Additionally, the audience at Staples Center will share the 3-D experience, wearing the same glasses as those being worn by viewers at home."
So if you go into Target (whatever that is LOL) then they should give you the correct ones.
