Rakish, the folk duo of Maura Shawn Scanlin (violin) and Conor Hearn (guitar), will provide the music at Tamper Wednesday Night, with this week’s menu featuring tacos. The restaurant will be serving from 6 to 9 p.m., with the musicians playing from 7 to 9.

The pair gets their name from the traditional Irish tune “Rakish Paddy,” an origin that aptly suits the duo and their shared background in traditional Irish and Scottish music. Maura Shawn, a two-time U.S. National Scottish Fiddle Champion and a winner of the Glenfiddich Fiddle Competition, wields the technical range of an accomplished classical violinist and the deep sensitivity of a traditional musician. Conor, a native to the Irish music communities of Washington, D.C., and Baltimore, makes his home in Boston playing guitar for a number of traditional music acts and bands.
