This past weekend, various acts headed to Arcosanti, Arizona for this year's FORM Arcosanti Festival—which was curated by Hundred Waters and Moses Sumney. The lineup included a handful of notable performers like Solange, Kelela, Thundercat, James Blake, and more. During the last day of the three day festival, James Blake closed out the show with a few unexpected surprises for the audience.

During his set, Blake performed a captivating rendition of Frank Ocean's track "Godspeed," taken from his latest album BlondeThe album version is rather simplistic in its own right, with very minimal production. However, Blake's cover featured just him and his piano—emphasizing the emotion in the lyrics.

Last May, before Ocean shocked the music world with the release of his visual album and official album, Blake revealed that he had been working in the studio with Ocean on new music. Now we know that Blake has writing and producing credit for at least three tracks on Blonde. The 45-second clip shows Blake pouring his own emotion into one of the songs he helped write, produce, and play keys for
