Arca has released a new track, 'Madre'.

Part of a new four-track single, the nine-minute 'Madre' sees Arca collaborating with cellist Oliver Coates. It appears on the new single alongside three alternate versions of the track: one that removes Oliver Coates' cello ('Madreviolo'), an acapella, and an instrumental of 'Madreviolo' ('Violo').

"I wrote 'Madre' years ago, and I did 'Madreviolo' playing the cello myself, before working with Oliver," Arca said in a statement. "After recording 'Madreviolo', I destroyed the cello I bought specifically for this. It had to be like a one-time thing for the version where I pitched up my vocal to castrati registers. But the original version with my unprocessed vocals, which felt a necessary version to share alongside 'Madreviolo' needed an arrangement that I could envision but couldn't hear.

"When I shared the acapella version with Oliver there was an insane resonance and chemistry; where he took it felt like the place I dreamed of but couldn't reach without him."

'Madre' is out now on XL, and you can watch a video for the song below.

Arca was recently nominated for a Grammy for her 2020 album 'KiCK i'.
