Patrick Green and Jill Schwartz in Ballet Quad Cities' CarmenAfter two years of Love Stories for its Valentine's Day production, Ballet Quad Cities changed things up this year by presenting Carmen, the story of a commanding woman who does what she pleases with men she fleetingly fancies. As with Love Stories, though, there was more than one piece performed this past weekend, with choreographer Margaret Huling's "Black Coffee" - a jaunty, jazzy number also featured in last year's Love Stories: Love on the Run - making up the first portion of the evening's entertainment.
