Far be it from me to fully understand why Los Angeles Mayor Antonio Villaraigosa felt the need to dump all over the District this morning. But, hey, it wouldn’t really be fair to people like Spike Mendelson if we didn’t call him out on it.

>> Artist Lauren Rice installs her take on good and evil, love and hate and the fear of and fixation with death in Heirlooms, opening at Transformer. See her gallery-wide installation that is both floral and decorative — created from window screens, newspaper, phone book pages, spray paint and glue — and is more like kudzu than a well-tended garden.
