In his first solo exhibition in Los Angeles, the artist who once created a picture for every page of Thomas Pynchon’s “Gravity’s Rainbow” (an epic undertaking he collected in a book) has a gathering of works that range from wild sci-fi worlds to erotic daily scenes from his life. Opens Saturday, May 9 and runs through June 6. Bergamot Station, 2525 Michigan Ave., No. B5A, Santa Monica, richardhellergallery.com.
