Combining elements of Caribbean mento and calypso with American jazz and rhythm and blues, Jamaican ska is the upbeat melodic embodiment of joy. The ’60s dance music is the foundation on which longtime Richmond group Murphy’s Kids has built its good name. On Saturday, Dec. 19, the band holds its 16th annual Skalidays holiday benefit concert at the Broadberry. The group is joined by a stellar collection of Jamaican influenced bands, including Richmond ska punkers Neighborhood Friendly, the roots reggae of Might Joshua and the Zion No. 5, dropping third, rock warriors Nesta and Norfolk-based soul revivalists Major and the Monbacks. Proceeds go to Performing Statistics, the Virginia community organization that connects incarcerated teens with artists, educators and policy advocates to transform the juvenile justice system. Canned food donations also will be collected for distribution by Food Not Bombs and FeedMore. Doors for the all-ages show open at 8 p.m. Admission is $10-$15.
