Katherine Bloom is an American singer-songwriter based in Litchfield, Connecticut, whose sad voice often accompanies simple folk melodies.

The daughter of oboist Robert Bloom, Kath grew up in New Haven, where she studied the cello as a child and started playing the guitar when she was a teenager. She collaborated with Bruce Neumann in the early '70s, but it wasn't until she met avant-garde guitarist Loren MazzaCane Connors in 1976 that she started recording. Bloom and Connors recorded multiple albums of fragile, simple folk and blues melodies, the majority of which were written by Bloom herself. Their collaboration ended in 1984 with the release of their final album, Moonlight, of which only 300 copies were pressed.
