Maryland-based rapper Brandon Perry, known as Knowledge Above All Nonsense (abbreviated to K.A.A.N), is best known for his cynical, twisted tracks and fast bars. His music is heavily influenced by the abuse he has experienced, including substances, his musical idols growing up, his depression and anxiety, and his struggle to grow his fan-base. K.A.A.N is not one to use simple language – his vocabulary is far larger than that of other rappers around and he flaunts it within his tracks often.
