The amphitheatre next door to City Hall plays host to a lunchtime concert featuring young ensembles and performers from across London.
The lineup includes Bexley Little Big Band, which features 16 brass and wind players from Bexley Music Service based at Bird College in Sidcup.
Also performing will be the Hounslow Brass Quintet.
Weather permitting, bring lunch and settle down for a great selection of Londonís up and coming young talents.
