Tonight brings another of those First Thursdays where all the galleries around downtown have openings and free wine and such. 111 Minna has a group show debuting tonight called, obscurely, The Presence of Absence. And we'd like to point you to a show by friend of SFist and local artist Joey DeRuy happening at 12 Gallagher Lane. See the interview we did with him in 2009, and stop on by the gallery to see a collection of colorful, provocative new works. The show will be on view for three months.
