Watch the 1975's Sultry, Soulful Cover of Justin Bieber's 'Sorry'

Manchester outfit mixes spacey synths, smooth sax lines on surprising BBC 1 Live Lounge performance

The 1975 delivered a surprising, yet pristine cover of Justin Bieber's "Sorry" during an appearance on BBC 1's Live Lounge

The 1975 turned in a slinking, surprisingly funked-out cover of Justin Bieber's "Sorry" during an appearance on BBC Radio 1's Live Lounge Thursday.

Anchored by an impenetrable groove, the Manchester pop-rock outfit put a spacey spin on the song with swirling synths and sopping guitar lines, while frontman Matthew Healy delivered a strained, crackling vocal performance.

The band's secret weapon, however, proved to be saxophonist John Waugh, who bleated out a slightly altered iteration of the song's indelible synth hook and accentuated the track with several appropriately smooth ad-libs.

The 1975 are set to follow up their 2013 self-titled debut with I Like It When You Sleep, for You Are So Beautiful Yet So Unaware of It on February 26th. In a recent interview with Rolling Stone, Healy and drummer George Daniel spoke about the natural evolution of the band's sound, as well as some of the lyrical similarities and differences between their two LPs.

"There's a knowing to this album in place of the naiveté of the first one," Healey said. "I think that's what I reference a lot. 'I never found love in the city.' 'You used to have a face straight out of a magazine.' There's a resignation to that hopeful naiveté in this record that replaces that. It's all about being the same guy. It's a world now. It's a community. It's a whole thing, the 1975. At least to us because we're in the middle of it."
