The xx’s week-long Night + Day residency at London’s O2 Brixton Academy, which wrapped up tonight, has already brought them together with Robyn and Cat Power. On Monday, it also led to an onstage collaboration with Savages frontwoman Jehnny Beth, who joined the band to sing their 2009 track “Infinity.” Watch below via Pitchfork.

On Monday night we were joined by our dear friend @jehnnybeth from Savages. She told us once that she loved our song 'Infinity' so we thought it would be fun to invite her up to sing it! One thing we aspire to do with Night + Day is to bring people together, from all different types of music, so to have her join us felt very special and it was a lot of fun adding distortion to everything at the end! Thank you so much Jehnny Beth for bringing your energy onstage, we had so much fun with you! xx The xx
