Coldplay's Chris Martin dropped by the Rolling Stone studio yesterday to chat about his band's fifth album Mylo Xyloto, a record which reunites the English quartet with Viva la Vida collaborators Markus Dravs and Brian Eno. This time around, though, Eno was less involved in production and more engaged in the actual performances. "Brian Eno has become, not a session musician, but a player," says Martin. "He loves to just stand in the circle and play with the band. So he's kind of more of a band member than producer this time, which is very fun." Martin also spoke excitedly about the band's collaboration with Rihanna on the new song "Princess of China," noting that her contribution is the best singing on the record.
