New music: Santigold ft Karen O – Go

It's been three years since Santigold's excellent debut album, Santogold (the "o" became an "i" following legal wranglings about her name) and since then she's collaborated with Christina Aguilera, Kanye West, Lykke Li, Devo, Julian Casablancas and Beastie Boys. Despite all this, there's been a lack of information on her follow-up album – until yesterday, when a brand new track featuring Karen O emerged on Jay-Z's blog. Accompanying the song is a lengthy interview in which Santigold discusses the problems of taking so long to follow-up her debut: "On one hand it's a challenge, beckoning any would-be usurpers to come show and prove. On the other, it's a call to myself to rise to the occasion." The song itself is a brilliant mix of chant-like vocals (reminiscent of MIA), pinging beats and a deliriously catchy hook. Karen O's presence? Icing on the cake.
