Interestingly, given their relative absence as performers from many
genres, it has been claimed that women dominate membership of a cap-
pella groups. This may be a reflection of a style not requiring technical
resources (instruments), and able to be undertaken, initially at least, in
domestic social settings. For example, Sweet Honey on the Rock are an
all-woman, African-American a cappella group, active since the mid-
1970s; heavily gospel influenced, their work comments on contemporary
political, social and personal concerns.
