Here's the description from 651's site:
Tamar-kali is a force of nature. Her musical roots lie in NYC’s hardcore rock and underground punk scene where she established herself as a dominant and original voice. Inspired by her longtime love of strings, Tamar-kali formed Psychochamber Ensemble in 1998. Tamar-kali’s mesmerizing vocals lead this all-female string ensemble through a haunting evening of deconstructed songs composed specifically for strings by Tamar-kali.
