Josh Tillman had had enough. Enough of Seattle, enough of his alter-ego J Tillman (the name under which he released a number of solo albums), enough of his relationship, enough even of Fleet Foxes, the band he’d drummed with since 2008. So he “blew everything up”, filled his van with hallucinogenic mushrooms and headed for California, where he moved into a shack in Laurel Canyon and began writing a novel.
