A nice little review of Roisin's Glastonbury performance from popmatters.com:
I stuck around the dance stages to see Roisin Murphy. I had only seen Ms. Murphy in her eccentric videos. Her unmistakable style, somewhere between Bjork and Britney, easily translated to a live setting, and she dazzled the audience with multiple costume changes.
She approached the stage with a robotic lurch not too dissimilar to Pee Wee Herman's "Tequila" dance and worked it through cuts from Ruby Blue and Overpowered. Her live rendition of "Ruby Blue" was particularly delightful, with the song taking on a '60s go-go sound.
