Cat Martino 'I Promise' (ft. Sufjan Stevens and Chris Powell)
Brooklyn songwriter Cat Martino isn't exactly a household name in her own right, but she's bound to earn some more listeners with her single "I Promise," which features high-profile guest spots from Sufjan Stevens and Man Man's Chris Powell.

This creepy electro cut comes via Weathervane Music's Shaking Through documentary series, which gives artist two days to record an entire song in its entirety, right down to the final mix.

Listen to the chilly track below, and scroll past that to watch the five-minute episode of Shaking Through to learn more about how "I Promise" came into being.
