Two years ago, four young painters and muralists collaborated on a series of new work for an exhibition called Almost Famous. Those same artists — Eric Inkala, John Grider, Keiko Yagishita and Isaac Arvold — are at it again with a follow-up exhibition, Almost Homeless. 3-Minute Egg went to the opening reception at First Amendment Arts — a gallery in the basement of a warehouse at Stinson/Broadway. The exhibition is up through April 22.
