Adele delivered a stomping live debut of 25 standout "I Miss You" on Friday (Feb. 12) during a pre-Grammy concert at Los Angeles' Wiltern Theatre. The singer also performed new tracks "Send My Love (to Your New Lover)" and "All I Ask" for the second time ever, Rolling Stone reports. Watch fan-shot footage above. 

A memorable performance of mega-hit "Hello," viewable below in another fan-shot clip, finds the singer earning some vocal rest, as the audience shouts virtually the entire song by themselves. After crooning the song's dramatic first word, Adele steps back, dancing around the stage and taking selfies with random people's cell phones. She does chime in with a couple lines at the end, but the crowd handles the heavy lifting throughout. "That was fucking amazing!" she says after. "That was a whole fucking song!" 

Adele will perform Monday (Feb. 15) at the 58th Annual GRAMMY Awards, along with acts like Kendrick Lamar, The Weeknd and Little Big Town.
