Singer/songwriters including Ingrid Michaelson [ tickets ], Sara Bareilles [ tickets ] and Cary Brothers [ tickets ] will unite for the fourth annual Hotel Cafe Tour [ tickets ].

The trek, scheduled to visit more than 35 North American cities in March and April, will also feature Joshua Radin [ tickets ], Kate Havnevik [ tickets ], Meiko, Priscilla Ahn, Dan Wilson, William Fitzsimmons, Jessie Baylin and Jim Bianco on select dates. Details about which artists appear at each show are available at the Hotel Cafe Tour website. More performers are expected be announced as the tour approaches.

The outing--billed as "one bus, one band and a bunch of friends on the road"--is set to launch March 6 in San Diego, and will travel across the country and back through April 12. The singer/songwriter spectacular will then head to Europe and Japan. US dates are listed below.

Hotel Cafe Tour founder Cary Brothers will perform at every show and play host to the plethora of artists. Michaelson, whose career got a huge boost last year when Old Navy used her song "The Way I Am" in a commercial, is also scheduled to play every US date.

The tour, named after Hollywood, CA's Hotel Cafe, was created to bring the vibe of intimate coffeehouse performances to fans all over the world. The music venue evolved from a small coffee shop and has become one of the premier singer/songwriter showcases in the US, according to a press release.
