Nicholas & Sheila Pye, The Departure, 2010, archival digital print mounted onto aluminum, 48″ x 48″, edition of 5.

>> Jessika Tarr and Helen Glazer will discuss their work — Monstrous and Clouds InFormation, respectively — tonight at Hillyer Art Space. The work by both artists is surreal and dream-like. Tarr’s illustrations are similar to those of German storybooks: dark and provocative, yet seemingly innocent in its imagery. Glazer’s clouds examine the illusion of stability and ever-changing reality. 7 to 8 p.m. $5 – $10 donation suggested.

>> We’re takin’ it to the streets at the Corcoran on Thursday. If you’ve ever wondered about all the tags you see while riding the Red Line or the other murals you’ve seen around town, then be sure to join Roger Gastman for a tour of the underground world of graffiti and street art and a discussion of the history of graffiti in D.C. On the scene since he was 14, Gastman’s sure to have a treasure trove of stories to tell. 7 p.m. Tickets $15, $10 for Corcoran Contemporaries.

>> The Canadian husband and wife team, Nicholas and Sheila Pye, are all over D.C. this week — starting at The Phillips Collection on Thursday with the opening of their exhibit The Coronation, a three-channel video displayed as a triptych in which the Pyes explore issues of gender and identity. That evening, there will be a screening of the duo’s internationally acclaimed trilogy The Paper Wall, A Life of Errors and Loudly, Death Unties. The films will be followed by a discussion with the Pyes and curator Vesela Sretenovic. No word on whether there will be pie. 6:30 p.m.
