If you haven't already been to the Dikeou Collection, chances are good that you'll never find it without a guide. The gorgeous gallery is hidden away on the fifth floor of a building just off the 16th Street Mall, and is a white maze of rooms filled with art installations of all mediums, occasionally including floor-to-ceiling inflatable pink bunnies. In the midst of all this, the Dikeou Collection holds intimate, donation-based shows — Sara Century, Cougarpants and Last Eyes played a recent First Friday gathering. The space's serene sterility as a gallery offers a nice, natural juxtaposition to the loud and sometimes wild performances by local musicians.
