As they do every year, the 2017 Grammys will use the same logic to book performers as kids do when filling up their soda at the fountain: If one flavor is good, then mixing in every single flavor imaginable must be even better. According to Pitchfork, A Tribe Called Quest, Dave Grohl and Best New Artist nominee Anderson .Paak are the latest collaboration scheduled to take the Grammys stage Sunday, February 12. Daft Punk and the Weeknd, as well as Alicia Keys and Maren Morris, have also been announced to perform, alongside Adele, Metallica, Keith Urban, John Legend, Bruno Mars, and Carrie Underwood. While the night will feature plenty of music's biggest stars, not all of them will be in attendance: Frank Ocean, Kanye West, Drake, and Justin Bieber have all either said or are rumored to be skipping the show for various reasons. Which is too bad, because you could really go for a mashup of Drake and Keith Urban right about now.

The Grammys might be losing more high-profile attendees. Frank Ocean became the most clear-cut dissenting voice against the awards ceremony when he failed to even submit his album Blonde for voting eligibility last fall. Ocean described the decision as his “Colin Kaepernick moment,” and said, “I think the infrastructure of the awarding system and the nomination system and screening system is dated.” Before that even happened, though, Kanye West said he would not attend the Grammys if Ocean wasn’t nominated. Now TMZ is reporting that in addition to West and Ocean, Justin Bieber and Drake will be skipping out on the Grammys, too. Drake and Bieber’s motivations are not clear — there has not been a statement of protest issued from either performer — but if it ends up they just decided to be elsewhere on Grammy night, that’s an indication in and of itself of where the broadcast lands on their priority list. If Taylor Swift is in attendance, expect a constant, picture-in-picture dance cam to make up for the waning star power.
