Ok - now here was a band with a very interesting history. This was a late 60s trio comprised of sisters who were pretty much forced into this by their father who was going by a prediction his mother had made years earlier. Musically, they were uneven and out-of-tune with very simple lyrics and that added to the charm of their sound. Before you can even get a chance to hate it it's already endeared itself to you. Haunting and innocent...
What's also interesting is how their sound predates that of lo-fi indie by a couple of decades. In fact, they've had an affect and influence on different indie bands that would later form and have inspired a tribute album. And Frank Zappa, himself, had even praised the band.
They very much had a unique sound. It's something I definitely dig and couldn't easily dismiss upon first listening.
