Lady Gaga kicks off another great artRAVE show last night in Milwaukee after her three week long break. As a part of the well known Summerfest, Gaga had to shorten the show, skipping a few songs such as 'Fashion!', and as a quick update, the stage could not use any of the gateways due to the different proportions of the venue. Check out HQ photos, fan photos and videos after the jump.
