After having performed it at Pitchfork's Music Festival last July, Low have now released a studio version of Rihanna and Mikky Ekko's hit 'Stay'.

The track has been made available digitally on iTunes via SubPop. Low's Alan Sparhawk and Mimi Parker took the parts as Ekko and Rihanna, respectively, and said they'd been practicing the song all week.

The money raised with the digital sales will go to Pitchfork Festival charity partner Rock for Kids, that provides music education to underserved children in Chicago. [via Pitchfork]
