dihedral cases
Emahoy Tsegue-Maryam Guebrou is a 98-year-old Ethiopian nun whose solo piano music came to prominence in 2006 as part of the Ethiopiques collection. She was trained in the western classical tradition though her music has been described as bluesy, freewheeling waltzes with the influence of the chants of the Orthodox Church. It might all sound a bit obscure, but it is well worth a listen.
