From Folkways:
Collected in County Down in 1960, these field recordings present the songs, processional music, and of course, the lambeg drum beats characteristic of Northern Ireland’s Protestant population. Samuel Charters’ extensive notes provide ethnographic accounts of the aesthetics of lambeg drumming, although they avoid much discussion of the drums’ inescapable political context.
No designer is credited, although it’s likely by Ronald Clyne, who designed most of the covers for Folkways Records. The art depicts the monument to Francis Crozier in Banbridge.
