Mac Miller posted an unreleased track to his Soundcloud today, called "Pet Sounds," which features Sean Price, the Brownsville rapper who passed away last week. On the track the late-artist raps, Fuck the king of New York, in my presence they all peasants. The track's artwork is a shot of a mural in Crown Heights which was painted last week. Most notably, the song is captioned with a message telling Miller's fans to donate to a crowdfunding campaign to help support Price's family. Listen to the track below and donate to the campaign here.
