Vampire Weekend keyboard player Rostam Batmanglij has written a "gay anthem".

The keyboard player publicly revealed he is gay, and told how he wrote the song with his side project, Discovery, last year which he hopes will one day become an "anthem" among the gay community.

He said: "With that song I was having fun, but at the same time it was honest - those lyrics are meaningful to me, they come from my heart.

"I was disappointed when it didn't become a gay anthem, but, you know, it's not too late."

Speaking about his main band's new record, 'Contra', Rostam, 26, said how the group worked to develop a postmodern feel for some of the tracks.

He added to Out magazine: "We wanted something very different from the first record. You hear '80s harmonies on Contra, and for me that was the challenge: to make it not just sound like the '80s but feel like the '80s too. Because of the way it's presented, with the sampler and choir, the song 'I Think Ur a Contra' sounds new but also nostalgic."
