The architectual style of Brisbane’s long-awaited replacement venue for the demolished Festival Hall will fittingly pay tribute to the older buildings of the city demolished in the 1980s.

The design features of Fortitude Music Hall, now being built on Fortitude Valley's Brunswick Street Mall on the site of the old Optus Centre, were unveiled on Wednesday.

Former Powderfinger bassist John Collins, who now runs the Triffid music venue at the Newstead end of the Valley, has been part of the project to replace Festival Hall, along with developer Scott Hutchinson.

Festival Hall was on the corner of Charlotte and Albert streets in the CBD and was demolished in 2003. The live music scene in Brisbane never recovered.
