Just when you thought Musics Biggest Night couldnt get any bigger... The Recording Academy announced Friday morning that Adele has joined the 2017 Grammys lineup. Its shaping up to be a big night for Adele, as 25 was the best-selling album of both 2015 and 2016. The compilation was released on Nov. 20, 2015, 15 months before the 2017 Grammys. She suffered technical difficulties last year while singing All I Ask. Adeles microphone dropped onto the piano keys, so the show switched to a backup sound system that caused the momentary audio drop.
