The first in a summer of musical Fridays at Pillars Park starts this afternoon, organizer Patrick Jones just reminded CHS. Tunes start at 4p. You can also stop by the Villa Apartments building to see the progress Derek Wu has made on his collaboration with art faculty and students from the nearby Northwest School. Northwest’s “Public Art class” has been working with Wu — also known as ERAS — to create the new mural on a face of Capitol Hill Housing’s Villa building overlooking the off leash dog area of the park. You might remember the “Abraham Obama” work CHS wrote about at the same location way back in 2009. Looking for more creative acts? You can also visit the demolition of the office building on Minor to make way for a new, brightly-hued mixed-use project below the Melrose Market. More information on the music series is below.
