The first official Peaky Blinders-themed festival will take place in Birmingham in September.
It will feature live music from Mercury Prize nominees Anna Calvi and Nadine Shah and Scots rockers Primal Scream.
A similar event last year, which was not approved by the makers of the show, reportedly left some fans unhappy.
"I wanted to put together a festival sanctioned by us but not to comment on anybody else's attempt," creator and writer Steven Knight told BBC News.
The Legitimate Peaky Blinders Festival will be held in Birmingham, where the show is set, on 14-15 September.
The BBC drama follows the fortunes of the Shelby crime family, starring Cillian Murphy as leader Tommy Shelby. The music lover recently guest-presented several shows on BBC 6 Music.
The event will see 200 actors recreate Peaky Blinders scenes live in the historic streets, warehouses and factories of Digbeth. There will also be fashion shows and a specially commissioned dance performance by renowned company Rambert.
The line-up for the five music stages includes Anna Calvi, who scored the fifth series of Peaky Blinders, which starts on BBC One later in the year.
