Bumpus was a mainstay on the club circuit in Chicago, and Yamagata soon landed a gig singing with the band. She spent six years in the lineup, recording three albums and touring the country along the way. By 2001, however, Yamagata felt her time with Bumpus had run its course. She had a solid batch of songs that didn't gel with the band's funkafied formula, and a solo career was soon launched.
In September 2002, Yamagata landed a deal with Arista's Private Music, and her self-titled EP arrived in October. Her first full-length album, Happenstance, followed in June 2004. Featuring production from John Alagía, who had previously helmed such albums as John Mayer's Room for Squares and Dave Matthews Band's Busted Stuff, the album's pop-tinged sound found its way onto several teen-driven TV shows, including The O.C. and Alias. Happenstance also endeared Yamagata to such musicians as Ray LaMontagne, Jason Mraz, Ryan Adams, Conor Oberst, and Rhett Miller, all of whom invited her to perform on their albums as Yamagata readied her sophomore effort. Boosted by such support, she returned in 2008 with Elephants...Teeth Sinking into Heart, an eclectic release that featured both intimate material and PJ Harvey-inspired rock. Yamagata used the crowdfunding website PledgeMusic to create her third full-length, 2011's laid-back Chesapeake, and again in 2016 to help fund that years highly anticipated Tightrope Walker. ~ MacKenzie Wilson & Andrew Leahey
