Famed Lower East Side graffiti artist Chico has started to paint over his Power of Peace mural on Houston St. near Avenue B. The first new part is of the band Losaida. Lyn Pentecost, executive director of the Lower Eastside Girls Club, which had commissioned the Power of Peace mural, said Chico is also planning a mural of the woman who owned the liquor store that the wall belongs to, and which has sported so many of his memorial murals over the years. (The woman died a few months ago.) The new Girls Club piece will promote the club’s existing bakery and also a new cafe the girls will be running soon.
