See Lorde Unleash Spirited 'Melodrama' Songs on 'SNL'

Singer performs "Green Light" and "Liability," makes cameo in "A Sketch for the Women"

Lorde served as musical guest on the latest episode of 'SNL,' performing two tracks - "Green Light" and "Liability" - and also appearing in a sketch.

Lorde served as musical guest on the latest episode of Saturday Night Live, playing two cuts off of her upcoming LP Melodrama, "Green Light" and "Liability. The performances marked the first time Lorde had played both songs live.

While Lorde wasn't technically making her SNL debut – in November 2015, she performed Disclosure's "Magnets" alongside the British dance duo for their musical guest spot – Saturday's episode also marked her first appearance as SNL headliner.

The singer opened things up with the spirited "Green Light," the first single off the June 16th-bound Melodrama, with Lorde – bathed in red light – backed by a group that included a trio of young singers.

For her second performance of the night, Lorde scaled things back for "Liability," her just-released ballad. Donning a wedding dress and sitting back-to-back on a bench with her pianist, the singer delivered a sparse, understated rendition of the track.

In addition to her musical performances, Lorde also popped up in the closing seconds of SNL's "A Sketch for the Women," where Beck Bennett and Kyle Mooney hijack her rendition of "Royals".

In an interview with Zane Lowe, Lorde revealed that she was inspired to pen the song after hearing Rihanna's "Higher" while in a cab; the track opens with the lyric, "Baby really hurt me / Crying in a taxi."

"I had a little cry and I was just like 'It's always going to be this way, at some point with everyone it's going to be this way,'" Lorde told Lowe. "But the song kind of ended up turning into a bit of a protective talismans for me. I was like, you know what, I'm always gonna have myself so I have to really nurture this relationship and feel good about hanging out with myself and loving myself."
