They march to promote the establishment of a 32 County Socialist Republic of Ireland.
The band alliance regularly organise events to commemorate Irish republican activists who have died for those politics.
The purpose of the meeting was to discuss the infamous battle that took place on 21 April on Victoria Road in Glasgow when republicans were marching in support of the blanket protest in Long Kesh.
As the march made its way down Victoria Road it came under sustained attack from Scottish loyalists, resulting in several band members being injured.
The organisation declared its support for former member and Provisional Irish Republican Army prisoner Michael Dickson imprisoned for an attack on the Osnabrück barracks in Germany and are the only republican organisation in Scotland to do so.
