PiA has posted a couple of covers of her songs by Japanese artists. I believe this is part of the promotional effort for her upcoming tour to Japan with Cheshire Cat.
This is a cover of PiA’s Ma Dog, and even tho it is only a preview, you can hear what a nice version it is, performed by the singer/multi-instrumentalist YeYe. (You can hear much more YeYe at SoundCloud and at her YouTube.
