What is "sleepercar"

Sleepercar is the alternative country project of Jim Ward, a member of Sparta and former member of At the Drive-In. Regarding the band, Ward has noted that: "I think it will always be “my” band. People can come and go as they please: I don’t want the stress of trying to maintain five or six happinesses, I love playing with the guys and when they want to move on, I will support them in whatever ways I can."
