A blues or jazz band—or any ‘jam band’ for that matter—operates using many of the design principles we’d like to see from a collaborative enterprise. Unlike an orchestra, a band is much more fluid in their interpretation of the music. They are able to improvise on the spot, blend sounds, and often play to the mood of the audience. In other words, they innovate, create mash-ups, and are responsive to users.
The metaphor of a jazz or blues ensemble to evoke a collaborative group. Cool. Nice lingo, and a raft of memorable images come to mind.
