They are a 3-person band from Singapore. From their SoundCloud write-up, seems CC would be just right up their alley wrt collaborations:
Pitch Feather is a musical endeavor by three good friends. With elements of indie, folk and rock, we explore and express the values of life through our songs.
We believe people have the power to take charge of their own lives and be free. With this spirit, we compose, record, produce and promote our own music all from our humble studio.

We are searching for opportunities to collaborate with other music, literal and visual artists. Do drop us a message to say hi! :)
