It’s time for the San Francisco Art Dealers Association “Introductions” again, and Catharine Clark Gallery has mounted one of the strongest Intro shows in years. In addition to the dilute ink paintings of Josephine Taylor, praised by Dale Hoyt in the following post, the video works of Bull/Miletic and leonardogillesfleur are noteworthy. Go this week so you can see Bull/Miletic’s SF Time Capsule projected (each video artist in the show gets one week on the big screen.) The visual rhythms of this lovely piece are syncopated with tart commentary, as when the camera rises buoyantly into the air only to snag, as if hypnotized, on a circling surveillance camera. Down the hall, Patricia Sweetow has collected a group of artists who make delicately obsessive work, including strapping tape abstractions by Mareth Hoferer and colored pencil paintings by Sid Garrison. Maria Park’s fizzy, bright acrylic-on-acrylite works, at Toomey-Tourell, are also worth a look. All three galleries are at 49 Geary Street in San Francisco.
