Wednesday night, T-Mobile presented seven-time GRAMMY-nominated artists Macklemore & Ryan Lewis, who performed to a sold-out crowd of 1,400 fans at the Belasco Theatre in Los Angeles.
The two performed hit songs, including "Thrift Shop," "One Love" and "Can't Hold Us."
The Seattle duo won major awards in 2013, including Best Hip-Hop Video at the MTV Video Music Awards, Rap Song of the Year at the Billboard Music Awards and Best Group at the BET Awards.
For the 2014 GRAMMYs, the duo is nominated for Best New Artist, Album of the Year, Best Rap Album, Song of the Year, Best Rap Performance, Best Rap Song and Best Music Video.
However, the Associated Press reported earlier this week most of the rap committee members believed the duo shouldn't qualify for the rap categories because of their "success on mainstream radio and their appeal in the pop world," according to one source.
The 2014 GRAMMY Awards takes place Sunday, Jan. 26 at 8 p.m. EST on CBS.
