David Bazan was, for many years, the songwriter and driving force behind the acclaimed indie band Pedro the Lion, building a dedicated following and selling a couple hundred-thousand albums based in large part on his extraordinary melodic sense and erudite, theologically-themed songs. After a decade helming the project,he found himself embroiled in a major personal philosophical and spiritual cataclysm, wrapped in a growing drinking problem. Bazan got to work exorcizing both his demons and angels, ditching the Pedro moniker in favor of his given name and producing two incredible pieces of work in the Fewer Moving Parts EP and the 2009 full-length Curse Your Branches (Barsuk). Branches is considered by many to be a legitimate masterpiece. Charting Bazan's increasingly skeptical struggle with the precepts of the evangelical Christian world in which he was raised, the album covers some pretty serious ground. NPR called it ''an album of great music and great humanity.'' Strange Negotiations focuses Bazan's energies toward the external, centering on his disappointment in the current state of accelerating American and global social fragmentation. Musically, most of Strange Negotiations sounds like a great rock band playing songs they're beyond intimate with. It's the first full-length he's recorded with a band, the same band with which he toured relentlessly in support of Curse Your Branches.
