I've found few that have all of the features. Finding one that is reflective but still conservative enough for a symphony concert is rare. CE back armor isn't as common as shoulder and elbow. The Tour Master Magnum Air seemed like the ticket, but darned if when I ordered it, they're sold out and discontinued! It looks good for warm weather too with all of the vents. I haven't found anything that fits all of the criteria as well.
I've been very happy with the Teknic Sprint convertible jacket for four season riding in Portland, OR. It's very waterproof, has some reflective material, has a zip out liner, has a zip out collar, and the outside zips off to leave you with an armored perforated jacket. It isn't leather though, I'm not a big fan of the pig skin 'cepting a track suit.
