Found an article about the most famous band room in the brass band movement. You’ll find it here http://4barsrest.com/articles/2006/art665.asp
The Black Dyke Band band room is a room filled with stories and famous tales (like the Bb-tuba player that used to warm up by playing tones so that the different photos would vibrate, cool!) that every banding person is interested in. For the rest of you … not as interesting i can assume.
