A woman and two other defendants have pleaded not guilty to murdering Tanveer Iqbal earlier this year and will face trial later this week.
Zatoon Bibi, 37, Gul Nawaz, 44, and a teenager whose identity cannot be released due to his age, all deny murdering Tanveer Iqbal on January 31.
A teenage girl will also face trial for perverting the course of justice by making a false statement to the police between January 31 and February 17.
Mr Iqbal’s body was found in the boot of his Renault Clio in the Edgbaston area of Birmingham on February 1 after going missing the day before after closing his shop, two days before he celebrated his 33rd birthday.
Mr Iqbal was a well-known producer in the city’s Asian music scene and ran the Hi-Tech Music shop in the same area with his brothers.
His brother said: “He was a very loving father of two lovely daughters, aged three and five.
“We want justice. If that doesn’t happen there will never be peace in our hearts.”
The jury has been sworn in at Birmingham Crown Court and the trial will start on Friday.
