Alt-rockers Cracker [ tickets ] have mapped out a headlining tour that runs through early December, as well as some new shared dates with "sister" act Camper Van Beethoven [ tickets ].

Cracker's late-year festivities kick off Halloween night (10/31) in San Antonio, TX. The band has 18 dates on its own lined up before hooking up with the Campers for four end-of-2008 split shows beginning Dec. 28 in San Francisco and concluding with a New Year's Eve affair in Portland, OR.

The two groups share singer/guitarist David Lowery, who will pull double-duty fronting both bands during the twin-billed evenings. All dates are below.

"Greenland," Cracker's seventh studio album, and first since 2003's "Countrysides," hit stores last June on the Cooking Vinyl label.

"This album is the most personal and is the most directly about my life, my own experiences, and those around me," Lowery said in a press statement at the time of the set's release. "I found myself asking whether I wanted to continue to be a musician and keep writing songs. Those questions were answered by writing this record."

Camper Van Beethoven's "New Roman Times," which hit stores in late 2004, was the band's first album of all-new material since 1989's "Key Lime Pie." The group officially disbanded in 1990, but reunited in 2002 for a national tour, after which it headed back into the studio. Cracker, Lowery's other project, continued as well.
