Coldplay wants to collaborate with Sam Smith and London Grammar.
Coldplay bassist's Guy Berryman, 36, has been keeping an eye on the emerging star and electronic pop trio as the top stars hope to work with them, reported Contactmusic.
"I love London Grammar, I think they're amazing, and Sam Smith's, he's amazing. Disclosure, fantastic. There's a lot of great music around at the moment," said Berryman.
Coldplay's frontman Chris Martin, on collaborating with other artists said, "It's not really specifically answering your question. I think there's some really great bands at the moment, which is really encouraging."
The 'Yellow' hitmakers released their sixth album Ghost Stories earlier this year and recently revealed that they are working on their next record, 'A Head Full of Dreams' which could be their "final" release.
