While living in Evanston, Vedder's family fostered seven younger children in a group home. In the mid-1970s, the family, including Vedder's three younger half-brothers, moved to San Diego County, California. It was at this point that Vedder, who had received a guitar from his mother on his twelfth birthday, began turning to music (as well as surfing) as a source of comfort. He particularly found solace in the Who's 1973 album, Quadrophenia. He said, "When I was around 15 or 16. . . I was all alone—except for music. " His mother and Mueller divorced when Vedder was in his late teens. His mother and brothers moved back to the Chicago area, but Vedder remained with his stepfather in California so he would not have to change schools.
