It’s been another memorable year of music in D.C., Maryland and Virginia—filled with giant stadium and arena rock shows, memorable R&B and pop performances, and some of the biggest hip-hop shows ever to take stage. Adding to the excitement for 2011 was a brand-new, state-of-the-art music venue in Silver Spring that will surely bring top-notch acts to the area for decades to come. Metromix's intrepid concert photographer Alfredo Flores offers his take on 2011’s ten best concerts based on visual spectacle, stage presence, artist rapport with audience, and, of course, the music. This year’s edition of his top picks contains a couple of firsts—two acts making multiple stops in the D.C.-area in the same calendar year, as well as one music gathering so impressive that two Top 10 entries came out of that show.
