The thing about the Borg Symphony "live"
is that it's always very different because we always have a different line up.

In addition to a very precise backing track made by the founding members
we always have supplemental guest musicians who have willingly been assimilated into the group. Each one is chosen for a special skill, (not necessarily musical) and they blend into the overall piece always staying within a set of pre-determined cues established by the sound and the visuals.

This gives us a lot of room for improvisation without getting out of control - the last thing that Cyborgs need! Each of the assimilated members wears at the minimum a mask and the more adventurous ones a full Borg costume.
