Single got onstage debut at Helping Hands charity concert

On December 16th, at the Microsoft Theater in L.A., Metallica held their third Helping Hands Concert benefiting the metal giants' All Within My Hands foundation. After an opening performance by Greta Van Fleet, the headliners played a unique two-part set — the first part, acoustic; the second, electric — that included the live debut of Metallica's recent surprise single, "Lux Æterna." While fan-filmed clips quickly flooded the internet, today (December 23rd), Metallica offered up official, pro-shot footage of the momentous runthrough. Watch above.

"Lux Æterna" is the lead single off Metallica's upcoming new album, 72 Seasons, due out April 14th. "[It] is an upbeat, kind of fast and joyous song, I would say," frontman James Hetfield has said of the high-speed throwback cut. "Really indicative of New Wave of British [Heavy] Metal stuff, so kind of a harkening-back-to-Eighties kind of riff. It's just fun and makes me move."
