k- os is Kevin Brereton, a rapper from Canada. He released his debut album in 2002, and has released three subsequent records.

‘Black Water’ is taken from his forthcoming release The Anchorman Mixtape and features Sebastien Grainger of Death From Above 1979 fame. It is good.

The tracklisting for the mixtape is not very Anchorman-references heavy, but it does feature Drake on one of the tracks. Have a listen to ‘Black Water’ below.
