>> SiteProjects DC, which we reviewed last month, is ongoing throughout the 14th Street NW stretch, with special events sporadically showing during its run. Since Tuesday, Kathryn Cornelius has been performing her Art Services (Waste) at venues along the corridor. Tonight find her at Hemphill Fine Art from 4:30 to 5 p.m., then at Gallery Plan B from 5 to 5:30 p.m. Tomorrow see the act at Adamson Gallery from 4:30 to 5 p.m., then squeeze into the 2nd floor bathroom in the same building to see her between 5 and 5:30 p.m., and finally in the almost similarly sized micro-gallery, Curator’s Office, from 5:30 to 6 p.m. Check out the web site for the SiteProject DC artworks and other upcoming events.

>> Take in tonight’s Artful Evening at the Phillips Collection with a lecture titled Freedom of Impression — Pennsylvania Artists and the New Style, and learn how these artists capture their love of the landscape, at 6 or 7 p.m. Alternatively, sit down for Impressionist New York and hear how American artists were influenced by the French Impressionists, at 6:30 p.m. Lectures free with admission.

>> Take in some art history of the français variety at Hillwood’s French Festival this weekend. Visual arts, dance, drama, customs and rituals from the 18th century are part of this celebration of Ms. Marjorie Merriweather Post’s artistic pleasures. The socialite — whose name you’ll recognize from the eponymous concert venue — used the local Hillwood Estate for her French (and also Russian) art collections. Stop by the family friendly festivities at 4155 Linnean Avenue, NW, a 20 minute walk from the Van Ness Metro, on Saturday between 10 a.m. and 5 p.m. or Sunday between 1 and 5 p.m. General admission is $25; $20 for members, $15 for students, and $5 for ages 6 to 18.
