The Holmes Brothers' unique synthesis of gospel-inflected R&B harmonies, accompanied by good drumming and rhythm-based guitar playing, gives them a down-home rural feeling that no other touring roots music group can duplicate. Brothers Sherman and Wendell Holmes, along with drummer Popsy Dixon (the falsetto voice), are the group's core members, although they occasionally tour with extra musicians. All three harmonize well together. The Holmes Brothers are so versatile, they're booked solid every summer at folk, blues, gospel, and jazz festivals, as they play a style of music that is a gumbo of church tunes, blues, country, funk, reggae, roots rock, and soul. Although people like Bo Diddley and especially Jimmy Reed were early influences on Wendell and Sherman, gospel music also played an important role in their respective upbringings.
