Lots of promise in the opening of A Visit from the Goon Squad

Jennifer Egan's much-praised "Visit from the Goon Squad" gets off to a promising start - a novel about low-lifes on the periphery of the music business (bit of a redundancy there?) - first chapter story of Sasha, 35, youthful looking, an assistant to a music producer, with a serious streak of kleptomania, she lifts a purse in a hotel lady's room, then returns it remorsefully, goes home with her (younger) date, whom she'd met through a Web site and whom she doesn't care for much, they have sex, she rifles through his wallet, that's about it - but told very artfully, Egan moving effortlessly between straight narrative of Sasha's evening and her later reflections thereon on the couch of her psychologist, Coz. Not sure what to make of the story - but Sasha appears peripherally in second chapter, focused on her boss (Sanchez?), a record producer in NYC, driving off to the suburbs to talk with a sister-group that's no longer very successful and full of angst about his sexuality and his broken marriage. Egan's novel has the potential to be really good, if she can bring these elements together and make this work truly a novel - I am a little concerned that the chapters may be stories strung together without any true plot development - and if she can make it an exploration of depth of character and not a voyeuristic tour into the dark side. Her capacity to use the psychologist (psychiatrist?) for reflection and insight seems a hopeful device. Style is definitely open and readable and funny at times.
