Genesis uses theatricality. Mumford and sons uses blues grassy band of brothers appeal. Adele uses her enormous vocal range and drama queenery. Feist appeals to folk music lovers but adds a pop feel.
Sistermonk is a conundrum. Obviously its a party, but whats the party about? It's funk, it's trance, but without drugs, and its nor quite hipster, though thats the crowd right now. Its world music, but not really. It's hippie, earthy crunchy, let's heal ourselves,yay, but not really.
Its not mythic rock like Genesis or Pink Floyd, who flamboyantly retell the stories of their generation.
SisterMonk is something very acoustic -a djembe at the heart of the music, a female lead, could be Womens' folk festival material, though whose going to relate to it - the lyrics are written by a man.
So there's that element of surprise. The lyrics are also imagistic. Ultimately, it's about the vibe, and the vibe is big and colorful.
