Daddy G from Bristol band Massive Attack, will be playing at tonight's club night, which has been organised to raise funds in the search for missing DJ Derek.
Last month, he spoke exclusively to ITV West Country about why he's added his voice to the campaign to find missing Bristol DJ Derek Morris.
He called his friend and "local hero" DJ Derek a "walking musical encyclopaedia".
The club night is happening at the bar on Corn Street where the 73-year-old was last seen nearly a month ago.
