A rapper who collaborated with his granddad on his new record has been inspired to donate half of the proceeds to charity after seeing first hand the effect of Alzheimer's.

Ryan Matthews-Robinson had always wanted to work with his granddad Robbie 'King' Robinson, 73, who entered the music scene in the 80's after coming to London from Jamaica.

The 24-year-old who performs under the name Ragz-CV, spent hours working at his grandparents home and saw how dementia was affecting his grandmother Maureen, 74.

Eager to help, Mr Matthews-Robinson who lives in south Croydon, pledged to donate half of the proceeds from sales of the EP titled Paying Homage to the King, to the Alzheimer's Society.

He said: "I used to see my grandparents about once a month, but then I started going once a week and I could really see how my nan was suffering.

"She would forget who I am and was forgetting who my granddad is. It is very scary and confusing for her and it is upsetting, so I want to use the EP to raise as much awareness as I can."

A fundraising event and launch party have been organised to mark the release of the cd, and the record will be available from most digital stores from September 10.

Mr Matthews-Robinson describes the record as "something for everyone to enjoy."

He added: "My granddad gave me all his original work on a cd and I rap.

"It has a real jazz feel which my granddad brings with his production, and with my touch it is just the right blend of old school and new school. I call it jazz rap."
