The image shows a group of people standing in front of a concrete wall with the words "Oakland Mum Seum Oca" written on it. The people are dressed in black t-shirts and are playing various musical instruments, including saxophones, trumpets, trombones, and drums. They are standing on a set of stairs and appear to be posing for a photo. Some of the people are holding signs or banners, while others are looking at the camera. The sky is blue and there are trees in the background.
