The band's first performance was at the BBC Radio 6 Music Festival. "This is our first ever gig and it's quite nerve-wracking to be not only playing your first gig but playing it live on radio as well," he told the crowd at the venue and the audience of 6 Music listeners. "But I suppose I should be used to it after all these years." The gig also saw the first exclusive plays of songs such as "The Selfish Giant" and "Mr. Tembo", Albarn also played Tomorrow Comes Today from Gorillaz eponymous debut album and The Good, the Bad & the Queen single "Kingdom of Doom" as well as "El Mañana" from "Demon Days" and the Blur B-Side "All Your Life". "The Selfish Giant", itself was particularly well received, and many people praised Khan's vocals that ebbed through in the live performance. In his track-by-track review, Matthew Horton of NME said: ""Celebrate the passing drugs/Put 'em on the backseat while they're coursing through your blood" – yes, 'The Selfish Giant' is about a nuclear submarine. Well, that's hard to get a grip on ("Waiting for the final call that's coming down the line," maybe?), but what 'The Selfish Giant' really sounds like is a refined goodbye over dub bass and piping organ, drifting into a chorus that's devastating in its ordinary heartbreak: "I had a dream you were leaving/It's hard to be a lover when the TV's on/And nothing's in your eyes". The sort of thing you hope isn't autobiographical." Dan Cains of "The Sunday Times" wrote: Featuring the treated voice of Bat for Lashes’ Natasha Khan on its chorus and opening with Albarn essaying a serpentine jazz motif on the piano, this track contains the album’s deadliest lyric (“It’s hard to be a lover when the TV’s on and nothing’s in your eyes”), which Albarn fought to have edited out, being later over-ruled by Russell. “I’d be like ‘I can’t be singing this, Richard. I can’t deal with the responsibility of that line.” And he went, ‘No, no, no, that’s one of the best things you’ve written.’ My missus (the artist Suzi Winstanley) was always like, 'I don't like that line."
