The band – composed of original members Roger Miller, Clint Conley and Peter Prescott along with Bob Weston of Shellac – will kick off their U.S. tour May 7 in Columbia, Mo., three days after On Off On is released on Matador Records.

They’re scheduled to hit their native Boston as well as Philadelphia, Vancouver, San Francisco and other major cities on the trek, which stretches through June 10.

Mission Of Burma formed in 1978 and released one full album, an EP and a couple of singles before breaking up in 1983 due to Miller’s severe tinnitus. Their legend and influence have grown to epic proportions in the two decades since, and in 2001 the band regrouped with Weston replacing original tape manipulator Martin Swope.

Although they’ve played scattered dates in the last couple of years, including 2002’s All Tomorrow’s Parties U.K. festival, this spring’s outing marks their first nationwide tour since reuniting.
