Mario Sorrenti makes a big, brash impression in MOMA’s “Fashioning Fiction” show with a series of pictures that have an aggressively adversarial but smartly informed relationship to traditional fashion photography. Nearby, the curators have displayed two of Sorrenti’s photo-encrusted diaries, dense collages of personal pictures and commercial outtakes that recall Peter Beard’s famous notebooks and offer an intriguing glimpse into the artist’s most intimate influences. Five more of those diaries, compiled between 1992 and ’98, are included in this show, but you might not even notice them because exploded versions fill every inch of the gallery’s walls. Sorrenti has re-created a densely layered installation of snapshots, work prints, magazine pages, Polaroids, and family pix that papered the wall of his former downtown loft. Punctuated here and there by framed photos,this overwhelming array skitters from nude self-portraits and baby snaps to sessions with Bob Hope, Drew Barrymore, Larry Clark, and the very young Kate Moss. It’s a privileged peek inside the artist’s brain, a view of creative chaos at once indigestible and irresistible.
