While the 56th Grammy’s are almost here, last night we were treated to whom all of the nominees for each category of awards. With the announcement of the nominees came a live concert featuring all of the artists you can imagine. Above we have Macklemore & Ryan Lewis’ performance of “Thrift Shop”, and after the break we have Katy Perry’s performance of her hit ‘Roar’. We’ll update the post as more content becomes available.
