From Jay-Z and Kanye West's new collaborative album 'Watch The Throne' through to magical onstage moments such as Jack White and Alison Mosshart joining Seasick Steve during his iTunes Festival performance, 2011 has been a brilliant year for duets and musical pairings.
Here, Gigwise pays tribute to our favourite hook ups of the year so far, from Battles' numerous guest vocalists on their second album 'Gloss Drop', to CSS's recent collaboration with Primal Scream's Bobbie Gillespie, through to some of this summer's biggest chart toppers with Kelis, David Guetta, Nicki Minaj, Calvin Harris and more.
