Sleeping by the Mississippi by Alec Soth is one of the defining publications in the photobook era. First published by Steidl in 2004, it was Soth's first book, sold through three editions, and established him as one of the leading lights of contemporary photographic practice. This MACK edition launches to coincide with the first exhibition in London dedicated to the series at Beetles+Huxley gallery, and includes two new photographs that were not included in the previous versions of the book. Evolving from a series of road trips along the Mississippi River, Sleeping by the Mississippi captures America's iconic yet oft-neglected 'third coast'. Soth's richly descriptive, large-format colour photographs present an eclectic mix of individuals, landscapes, and interiors. Sensuous in detail and raw in subject, Sleeping by the Mississippi elicits a consistent mood of loneliness, longing, and reverie. 'In the book's 46 ruthlessly edited pictures', writes Anne Wilkes Tucker in the original essay published in the book, 'Soth alludes to illness, procreation, race, crime, learning, art, music, death, religion, redemption, politics, and cheap sex.' Like Robert Frank's classic The Americans, Sleeping by the Mississippi merges a documentary style with poetic sensibility. The Mississippi is less the subject of the book than its organizing structure. Not bound by a rigid concept or ideology, the series is created out of a quintessentially American spirit of wanderlust. Thirteen years since the book was first published, the artist's lyrical view has undoubtedly acquired a nuanced significance - one in which hope, fear, desire and regret coalesce in the evocative journey along this mythic river.

By way of follow-up to his critically acclaimed debut monograph "Sleeping by the Mississippi," Alec Soth turns his eye to another iconic body of water, Niagara Falls. And as with his photographs of the Mississippi, these images are less about natural wonder than human desire. "I went to Niagara for the same reason as the honeymooners and suicide jumpers," says Soth, "the relentless thunder of the Falls just calls for big passion." The subject may be hot, but the pictures are quiet, the rigorously composed and richly detailed products of a large-format 8x10 camera. Working over the course of two years on both the American and Canadian sides of the Falls, Soth edited the results of his labors down to a tight and surprising album. He depicts newlyweds and naked lovers, motel parking lots, pawnshop wedding rings and love letters from the subjects he photographed. We read about teenage crushes, workplace affairs, heartbreak and suicide. Oscar Wilde wrote, "The sight of the stupendous waterfall must be one of the earliest, if not the keenest, disappointments in American married life." Niagara brings viewers both the passion and the disappointment--a remarkable portrayal of modern love and its aftermath.
