Foo Fighters opened the virtual event with a four-song set, featuring classics ‘Everlong’ and ‘The Pretender’ as well as new tracks ‘Shame Shame’ and ‘Waiting On A War’ from their upcoming album ‘Medicine At Midnight’. Watch their set below.

Among a host of past footage, Eilish then played the second original set of the night, performing her three most recent singles, ‘Therefore I Am’, ‘My Future’ and ‘Everything I Wanted’. See her performance below.

Eilish also recently released her long-awaited collaboration with Rosalía – ‘Lo Vas A Olvidar’. The track, written for HBO show Euphoria, comes ahead of the singer’s second album, the follow-up to 2019’s ‘When We All Fall Asleep, Where Do We Go?’.

In a new interview, Eilish, whose fly-on-the-wall Apple TV+ documentary The World’s A Little Blurry is released next month, suggested that the new album is more honed than her debut.

Talking to Vanity Fair, the 19-year-old star said that her new music “feels exactly how I want it to”.

“There isn’t one song, or one part of one song, that I wish was this or that I wish it was that,” she said.

Foo Fighters, meanwhile, performed ‘Times Like These’ as part of Joe Biden’s inauguration as president last week (January 20).

Reviewing the event, NME wrote: “As has become the norm in emotional times, Foo Fighters delve into their back catalogue and pull out a classic. Before they launch into a heartstring-tugging version of ‘Times Like These’, Dave Grohl follows up a VT of a teacher in Seattle by paying tribute to educators across America, including his mum Virginia, for their work during the pandemic.

“Then it’s back to the business of rock, delivering a version of the band’s 2002 banger that slowly builds until it erupts with pure euphoria – a perfect reflection of 2020’s drawn-out run to Biden being named the election’s victor.”
