Haim had their mind blown after playing a show in London.
The band, made up of sisters Danielle, Alana and Este Haim and drummer Dash Hutton, released their first album Days Are Gone last year and have quickly garnered international success.
They took home the NME award for Best International Band recently and are lapping up the attention they're receiving in the British capital.
"I've never been mindblown after a show and I'm completely mindblown and I don't even know what's going on right now and [Primal Scream star] Bobby Gillespie is in my dressing room and I have no f**king clue how that happened because I'm the biggest Bobby Gillespie fan and, on top of everything, he told me that he liked how I ran onstage..."
Alana rambled to Britain's NME magazine after playing a packed gig in Brixton, London.
The musicians have won praise for their folk-rock sound and have a reputation for speaking their mind and having fun.
They've previously attributed their success to all those who ever doubted them and are busy preparing to tour the US for the first time, when their shows kick off next month.
"We finally get to go home! We haven't even done one tour of America. [Starting over] is the fun of being an artist. It's about finding your way to play bigger shows. I'm excited," Danielle exclaimed.
The band originate from California and have played on top US TV show Saturday Night Live.
They have a huge fan base across the pond and feel a strong connection with their fans in Britain.
"We just got a plaque [in the dressing room] that has posters from all four UK tours... It's crazy that we've sold out every UK tour we've been on. So f**king nuts. I'm f**king mindblown," Alana laughed.
