The birthday bash will begin on his actual birthday on Friday with tribute shows and special events and will culminate with a performance by Andra Day on Sunday.

Otis' family are overseeing the celebration and Grammy nominee Day admits she was honoured to be invited to close the party.

"Otis Redding is a legend whose career has transcended decades of music and influenced so many genres," Day tells Billboard. "As an artist rooted in soul, it is an honour to pay tribute to the legacy of one of my forefathers."

Redding's daughter Karla reveals she reached out to Andra because she can hear her father's influence in the singer's voice.
