Being cooped up in a bus with the same people 365 days a year is bound to cause tension. Add in the fact that life-altering decisions have to be made collectively, but the consequences of which take places individually. So it's absolutely no wonder ... or fault of anyone involved ... that from time to time members have to bid farewell to their musical families and take separate paths.

Most recently, Edens Edge founding member Hannah Blaylock parted ways with her bandmates Dean Berner and Cherrill Green, while in 2006 -- after a decade as a threesome -- Heidi Newfield announced she was leaving Trick Pony cohorts Keith Burns and Ira Dean to pursue a solo career. Everyone remembers that Sugarland was originally a trio, with Kristen Hall exiting after only one single, but you may not be able to guess which Rock and Roll Hall of Famer was an original member of a certain legendary country group.

Kristen Hall in Sugarland
After only one single, Kristen Hall exited Sugarland in 2006. However, that wasn't the end of the story, in 2008 she filed a lawsuit against former bandmates Jennifer Nettles and Kristian Bush, insisting she'd been promised a cut of future earnings. The lawsuit settled in 2010 for an undisclosed amount.

Marty Raybon in Shenandoah
Shenandoah was formed in 1984 and garnered several hit singles, but in 1997 lead singer Marty Raybon began working on solo projects. Though he toured with the band through the end of the year, his plan was to exit the group, which thus dissolved. In 2000, two of the original members reunited, adding four other members to be the new incarnation of Shenandoah.

In 2010, Love and Theft founding member Brian Bandas announced exclusively through The Boot that he would be leaving the trio. After five years, and a top 10 hit with 'Runaway,' the Austin native decided to to follow his own musical path, a decision sparked by the closure of the group's label, Lyric Street Records. Remaining members Eric Gunderson and Stephen Barker Liles went on to sign with Sony Music Nashville and earn their first No. 1 with 'Angel Eyes' in 2011.
