Ed Ruscha signing at Book Soup

There may not be another painter that has captured the feeling of Los Angeles better than Ed Ruscha. He’s wrung resonance from gas station signs, loneliness from advertisements and epic wonder from the most tedious urban detritus. Here he signs a loving retrospective of his work, “Ed Ruscha: Fifty Years of Painting,” with texts by James Ellroy, Richard Wagner and many others. Book Soup, 8818 Sunset Blvd., West Hollywood. 7 p.m. Saturday. www.booksoup.com.
