Also performing: Bruce Springsteen and the E Street Band and the Beach Boys, who are teaming up with Foster the People and Maroon 5 for a mash-up of old and new hits.
"It'll be interesting to see them try to play to all audiences," Grein said. "You've got veterans from back in the day playing inches away from groups that are current and hot right now."
Kanye West is nominated for seven awards. He may not win them all. Rut-roh. The rapper has had some infamous backstage blowups at award shows (and let's not forget his mic-snatch at the 2009 MTV VMAs) but this year might be different. "He's already said that he shot himself in the foot by releasing two records this year -- 'My Beautiful, Dark, Twisted Fantasy' and 'Watch the Throne' with Jay-Z," Comer said. Both are nominated for rap album of the year, which means he might end up splitting the votes.
Grein noted, though, that after "M.I.A.'s little moment at the Super Bowl, yes, I think you have to expect an outburst from someone. You get attention that way."
The Grammys wouldn't be complete if Lady Gaga didn't arrive in an egg or wear a meat dress or do something similarly outrageous. She's nominated for album of the year, but her attendance isn't guaranteed. "She's getting ready for a big world tour that was just announced Wednesday," Comer said. "She might show up, or she might want to save her energy. If she does make it, I'm sure there'll be a surprise." A shell fish corset, perhaps?
