The Sisters, and their backing group, the Boys, have been popular performers in the Kamba area east of Nairobi since the mid-'70s. Their music is like Kenyan benga, but incorporates a rhythm guitar accompaniment that is distinctive to the region. The group had a big hit with "Katelina," which even received airplay in Europe. Many of their songs address issues such as infidelity and single motherhood. Although the Sisters have now disbanded, the Kalambya Boys, led by Onesmus Musyoki, have continued to record and release albums.
