Pearl Jam bassist and founding member Jeff Ament and his brother, designer Barry Ament, will hold nine book events in the US and London to mark the release of Jeff’s visual memoir, “Since Forever”, on 25 September. The events will feature conversations, unseen images and discussion of the brothers’ long creative partnership, highlighting the book’s account of Pearl Jam’s early years.

“Since Forever” contains more than 250 black-and-white photographs, around 90% previously unpublished, largely taken between 1990 and 1998. The project grew from efforts to preserve Jeff Ament’s ageing negatives and documents life on tour, backstage and in the studio; events are planned for Ohana Festival, Seattle, Chicago, New York, Boston, Philadelphia and London.
