The brand new foyer is due to open in the middle of May
One Bristolian will have the chance to be a VIP for the day and open the doors of the new Colston Hall.
The building has now been officially handed over to staff who are fitting out the interior ready for public use later in the year.
The music venue has played host to music legends from The Beatles to reggae pioneer Bob Marley.
The competition asks people to say, in no more than 50 words, why they would like to open the new foyer.
Part of the relaunch of the concert hall includes a piece of permanent artwork made with pin badges donated by the Bristol public.
Over 3,500 music badges have been embedded into the wall surface, creating a star constellation chart of bands and music genres associated with the history of Colston Hall.
Michael Brennand-Wood, the lead artist for the project, told BBC Radio Bristol that the artwork reflects the building's musical past.
"There's an incredible sense, when you walk into the building, that the walls are embedded with all of these different types of music by different types of people over a long period of time, and I wanted to back reference that in some way."
The new multi-million pound foyer is funded by Bristol City Council and Arts Council England and will be opened at a sneak-peek preview event by a Bristol resident on Saturday, 16 May 2009.
Graeme Howell, Colston Hall's director, said: "This is a building for everyone. It is everyone's space, so we're looking for a member of the public to take part in this symbolic ceremony to hand the venue over to the city.
"We're looking for someone who has a special memory or connection with the Colston Hall, or an amazing vision for how they would like the new foyer to work in the future."
